'Maddox. Fuck!' A slam judders through the earpiece, followed by a shear of silence. I don't care if he's cut me off to save his skin. I know they won't leave me here—not after what it cost GC to create me.

I scoop the cat up into the crook of my arm. She hangs, trusting and boneless in my armoured grip. She's still purring. I heard cats do that when they are just about to die, to comfort themselves.

'Hold on, Mir,' I say, soft. 'Wait till you see your new home. Cat food galore.'

I head for the stairwell. Against its concrete steps, the heavy cadence of booted feet approach the fourth floor. In between the soldier's unsteady tread, the rapid, thin clack of Blue's stilettos. The pair breach the landing of the floor below me. Between the broken railings I have a clean shot. I take it, the silencer doing what it says on the box. Blue's oppressor drops, his weight yanking her down with him. She panics, frantic, struggling to free herself from under him. Her eyes find me as I step out of the shadows holding the pistol up against my helmet in a silencing gesture. Her eyes rake over me, pausing on Miro, still hanging, quiet in my grip.

'Ryan?' she whispers, my name on her lips almost undoing me. Hope blossoms from her, brightening her eyes, radiant with sudden tears.

I don't answer. I lift the pistol over my head, and point it towards the top of the stairwell. She's trembling. Her stilettos come off and she runs barefoot and sobbing up the stairs, desperation bleeding from her. I holster my pistol, take her outstretched hand and lead her onto the roof. As I close the rusting door behind me I run a quick thermal scan of the stairwell. Nothing lights up apart from the cooling body of Blue's oppressor. We're clear.

Hovering on the other side of a scavenged ventilation shaft, the shuttle waits for us. The door to its cabin slides open. I bite back a shudder of relief, having half expected de Pommier to put the shuttle's welfare over mine. I hurry Blue through the wreckage, desperate to get her away from this hellhole before it's too late. I lift her in, her weight so slight I endure another deep, burning surge of guilt. With Miro still tucked into the crook of my arm, I haul myself in, my attention fixed on the surrounding rooftops for anyone who might have seen us.

Silence greets me, palpable, dense with lethargy and starvation. I realise in the last six months, London has turned into a graveyard, with only those in the UFF still left alive, and by the look of Blue, barely. The door slides closed in total silence. I back up, still wary, watching the door to the stairwell, tense, willing it to stay shut, willing my gamble not to fuck up.

A shimmer ripples along the walls of the shuttle and a message scrolls across the inside of my visor confirming cloaking has been enabled. The shuttle ascends, steady, silent; the city's ruins shrinking, fading, smearing until only the inky, polluted sprawl of the Thames River reflects the faint white light of Earth's long-dead companion.

The line clicks on again. 'You are in so much shit, Maddox,' Akron snaps. The line cuts out. I'm fine with the silence because I'm not sorry. I would do the same thing again. I glance at Blue, who huddles, bloodstained, bony, and shivering in her seat, eyeing me, raw, naked with hope. For her, I would do anything.

I hand Miro to her. She takes the cat, settles her on her lap and pets her, absent. I know she's waiting for me to take off my helmet, for me to tell her what's happening. She's going to have to see me sooner or later. I pull the helmet off. Disappointment floods her face. She looks away and bites her lip.

'I thought you were—' she shakes her head and a tear slips free. I can't bear it. I long to take her into my arms, to hold her, to soothe her. But I can't. I'm a stranger to her.

'Ryan Maddox?' I ask, quiet.

Her eyes meet mine, her look a strange mix of surprised and wary. She pets Miro, retreating into herself, defensive. 'You knew him?' she asks, soft.

Knew. I nod and set my helmet on the seat beside me. 'Better than most.'

She blinks and catches her lower lip again with her teeth. Her eyes well up, laden with tears. She blinks again, harder, forcing them back.

I lean forward and rest my elbows on my knees. 'He told me about you.' I nod at Miro. 'And your cat.'

She says nothing. I wait, watching her, every part of me tingling, alive, aware. Blue. My only love. If only you knew what I have become. I am right here, with you. I will never leave you alone again. I swear it. I will protect you to the end.

'Thank you for not leaving Miro behind,' she whispers, her tears breaking free. I watch them fall, helpless, in agony. She turns away and looks out the window, her slight body shuddering. Exhaustion claims her. I open the compartment in the armrest beside my seat. Inside, a syringe filled with a sedative. I don't want to do it, but I have no choice. de Pommier was adamant, and after the stunt I just pulled, I dare not risk pissing her off even more.

I let Blue sleep until we reach the shadowy coast of Greenland, its fjords locked in winter's endless darkness. I watch her, contentment suffusing me as she drifts in the world of dreams, relishing the sight of her, ragged, starving, but safe and alive, Miro curled up beside her. I wish for the hundredth time I had a blanket, or some food to give them, but there is nothing.

I kneel beside her. My armour creaks, quiet. She wakes, and sits up, shuttered and defensive once more. My heart clenches.

'I have orders to sedate you,' I say.

She looks down at the slim syringe, nestled against my black-gloved palm.

'Where are you taking me?' she asks, her eyes coming to mine. A flicker of fear, suppressed.

'Alpha VII. A beautiful apartment. I've seen it. It has an artichoke lamp. Very, very rare.'

A flick of her eyebrow. 'Never heard of those. And the sedation?' she asks, low.

'Your arrival is Q Clearance. Only me and my team know you are alive.'

Her eyebrow lifts. 'Then how will you be bringing me in?'

'A tech container,' I say, nodding at a silver box, the size of a washing machine strapped to the floor behind her seat, its lid closed with metal buckles. 'It's a twelve minute transfer.'

She lets out a shaky breath and drops her gaze from mine to the cat. 'What about Miro?'

'I'll figure it out,' I say. 'A cat is easier to hide. She will be there with you when you wake up. I promise.' I mean it, too. If I do anything for her, it will be this, and to hell with the consequences.

'If Ryan were here instead of you,' she says, her eyes coming back to mine, 'would he give me this?'

Her question almost finishes me. 'He would. He wouldn't want to risk losing you again.' I long to touch her face, to press my lips against hers. I look back down at the syringe, afraid she will see the longing burning in my eyes. It's unbearable: having her so near, yet so far.

'Will there be food for Miro?' she asks.

'So much food,' I say, desperate to reassure her, 'and for you, too. Anything you want, you will have it.'

'I want Ryan,' she whispers, mournful, as she holds out her arm, exposing the blue line of her vein to me. I keep my eyes on my work as I swab the spot and ease the needle in, gentle, and give her the dose. Her words seep into my soul, tormenting me.

She sags, the drug hitting her skeletal body almost instantaneously. I collect her into my arms and move back to my seat, cradling her in my lap, her head against my shoulder.

'You have him,' I murmur as I bend to brush my lips against hers, my heart clenching so hard, I can barely breathe. 'Blue. I'm right here.' I kiss her again, despairing, silenced, her love lost to me the moment I died. I hold her tight and grieve for what we have become. Torn apart. Alone. Together.

January 2082

Twelve years, and still nothing. At forty, Adiana remains as beautiful as ever, despite food shortages over the last two years leaving her thinner. She sits across from me, picking at her food, the translucent golden dust powdered over her high cheekbones glittering in the candlelight, granting her a regal bearing, like an Ancient Egyptian queen. She looks up at me, catching me watching her, her eyes saying what my heart cannot: We will never be granted permission to be together.

It's my forty-second birthday, I have torn a hole into my savings the size of a house to afford our dinner at Alpha VI's finest restaurant, Le Cercle. She picks at her elegantly plated food, toying with the thin slices of cultured filet mignon arrayed over a bed of caramelised beets, tears glistening in her eyes, her pain palpable, boring into me, stripping me of the last of my hope. She's going to end it between us tonight. I can feel it in my bones.

'Amadi,' she begins, soft, her eyes on mine, mournful, resigned. 'We can't go on like this. We are out of time. You know as well as I the cut-off for me to have a child is forty-one.'

I don't want to hear it. Not yet. I lift my glass. 'Just give me a little longer,' I say, low, glancing away from her at the half-empty racks within the glass-walled wine cellar. 'The situation along the barrier is . . . difficult. But in a month or two, when things are under control, I will have time to push our case again. . .' From the corner of my eye, I watch her take her glass by its stem and sip. Her lips are trembling. She sets her wine back down and looks away, in the opposite direction from me, towards the exit. The tension thickens between us as she fiddles with her napkin. I realise she is considering walking out. My thoughts race, desperate, seeking for something, anything to offer, to stop her from doing what I know she is going to do.

She sets her napkin on the table. 'It's been almost eight months since we last met. The time before, I waited half a year to be able to see you for three hours. I can't go on like this, the not knowing, the waiting, the years dwindling away. It's agony.' A tear slips free. I reach out and brush it away with my thumb, gentle. She quavers against my touch. Her eyes close. 'I love you. So much,' she whispers. A heartbeat passes. I hold my breath, willing her to change her mind. She pulls away from me and slides her chair back. A moment later she is standing before me, quaking, clutching her handbag against her torso, defensive. I rise.

'Please. Sit down,' I murmur, my heart clenching so tight, it aches. With both hands I reach out to her, imploring her to stay. She steps back, eluding me, shaking her head, slow, her dark eyes brilliant in the candlelight. Le Cercle's wealthy clientele eye us, surreptitious, one of the men looks away, uncomfortable, his wife's gaze on Adiana laden with empathy. Wedding bands glint on their fingers. I realise, far too late, my awful blunder. Apart from several tables populated solely by high-ranking government officials, we are surrounded by married couples. Bringing Adiana here has only rubbed salt into a raw, bleeding wound. I glare at the other couples, fierce, daring them to leave their comfort zone, to face how the rest of us are being forced to live.

She shakes her head, ragged, broken. 'When you told me you'd booked a table here I thought the wait was over.' Her stricken look slams into me. 'I thought you were going to propose.' She blinks, hard, her lashes spiky with unshed tears. She shakes her head again. 'I can't live like this anymore. I've thought about it a long time. It's better for both of us if we move on. Alone.'

She sobs, and it cuts me in half. With a last, long, shattering look, she turns and stumbles to the door, her devastation so potent it shears through the dining room in total silence, like a nuclear detonation. I stagger, and look around me, numb, disbelieving, a sense of unreality shrouding me. Muffled weeping seeps from the next table. The man shoots me an unreadable look as he murmurs reassurances to his wife, telling her not to feel guilty. Stunned, helpless, I let the woman I love go knowing there is nothing I can say. Knowing I failed her.

I drain both glasses of wine, pay the bill, and emerge onto the city's empty, lonely streets, blinded by anguish, emptiness, hopelessness. Without her, I have become purposeless. I am no one. Nothing.

‡

Two days later I'm in the war room of the barrier's headquarters, listening, grim, to the emerging crisis developing along the stretch of wall north of the dried-out basin of Baker Lake.

'The time has come to take action,' Major Akron says, glaring at me, hard, his eyes cold, steely. The eyes of a man comfortable with killing. 'At last drone count,' he continues, relentless, 'the number of exclusion zoners massing at the boundary have swelled to almost a half million.' He picks up his coffee from the table, and takes a sip as he comes towards me, where I am seated at the end of the long conference table. 'And they aren't alone. More are coming. A hundred clicks south of Baker Lake, another four hundred thousand are on their way.' Against the opposite wall, a screen scrolls images of the vast heave and swell of the wretched mass of humanity clustering along the base of the barrier. Akron leans his hip against the table, and nods at one of his men, a fit, hardened soldier, a few years younger than me, dressed in smart Delta Force fatigues. He waits by the closed door, his hands clasped behind his back. 'Captain Ryan Maddox's team is ready to use lethal force to push them back. You are in good hands. Captain Maddox and his men represent the best of Global Command's Delta Force. Just give us the word.'

I catch the blue-eyed glance of Captain Maddox as he nods at me from under his beret. 'Sir.'

I ignore him. My gaze strays back to the wall screen. The image of Adiana's stricken look just before she left Le Cercle fleets through my mind, unbidden, damning me afresh. I clench my fists, willing it to stop haunting me, hating myself for trying to contact her late last night on the sat phone. She let it ring for a full minute before I gave up. Guilt bubbles up, hot and oppressive. I would have made her suffer all over again, forcing her to avoid me. I vow never to call her again.

On the screen, a fight breaks out near the wall. Someone lifts an AK-47 into the air and begins firing at the barrier, sweeping the gun back and forth at arms' length over their head. The bullets ricochet off the barrier's shield back into the crowd. Further back, bodies crumple. Pandemonium breaks out.

Akron sips his coffee again. He sets the mug down on the table with a quiet thud. 'Major Ezenwa,' he says, pulling my attention back to him. 'Let my men do their job. I would rather not have to escalate the matter. We have our orders to contain this.' He lifts an eyebrow and adjusts the position of his coffee mug, so the handle sits at a perfect ninety-degree angle to the table's edge. 'We both know meeting you is just a formality.'

'Just do what you need to do to push them back,' I snap, bridling at his condescension. 'It's hot as hell out there. With the lakes and rivers dried up, they won't last long.'

'Don't be so sure.' Akron mutters, dry, his eyes going back to the screen. 'There's a UFF convoy bringing drilling equipment from Yellowknife. Looks like they plan to settle in, right on our doorstep.' He glances at the closed folder under my hands, meaningful, the one I was supposed to have read this morning.

I say nothing. Instead I get to my feet. First Adiana. Now this. Everything is falling apart, my life mirroring the chaos of the world. I pick up the folder and go to the door. Captain Maddox steps back and opens it for me, deferential, polite, his eyes avoiding mine. I decide I hate him.

'Push them back but do not use excessive force,' I say. 'There are women and children out there.' I pause before continuing, sickened by what I am about to order. 'And take out the convoy. If they don't have water, they will have no choice but to leave.'

Akron suppresses a smile. Satisfaction oozes from him. He salutes me, sharp. 'Sir.'

I walk away, my grip on the folder tight. I'm an engineer, not a soldier. I'm not cut out for this. In my office, I close the door and pour two fingers of whisky. I swallow it all in one go. It helps to smooth the jagged edges inside me, but not much.

Out on the helipad, the steady beat of chopper blades cut through the broiling air. I pour another finger of whisky and knock it back, the amber liquid burning my throat. I will its heated fire to cleanse me of my crime, even as I watch Maddox load up his men, armoured and bristling with weapons—killing machines prepared to mow down thousands of innocents with my permission.

The private line of my sat phone rings. I glance at it. It's Adiana's number. My heart judders to a halt. I nearly answer it as the choppers lift off. I pull back. I'm dirty now, just like Akron. My father would be so disappointed in me if he were still here. For the first time in my life, I'm glad he's not. I punch the decline button. The panel's backlight dims.

In the distance, the thrum of the choppers fade, melding with the hum of the air conditioning system. I open the file and start to read.
