The ceiling tiles are wrong.

That's the first thing Marcus registers through the chemical fog—the ceiling tiles are a different shade of white than the ones in the prep room. A softer white. Cream-white. The kind of white that costs more per square foot than the institutional gray-white he fell asleep under. His eyes track the pattern, a faint grid of tiny perforations, and somewhere in the blur between sleep and waking he thinks: this is a nicer lab than I remember.

The second thing is the cold.

He's lying flat on his back on something metal and unforgiving. An exam table. The chill seeps into his shoulder blades, his spine, the backs of his thighs. He shivers, and the shiver moves through him differently—a lighter tremor, less mass to shake. The observation sits in his brain like a pebble in a shoe: that felt wrong.

He tries to lift his head.

The room swims into focus. White walls. A counter along the far wall with a sink and a row of glass-fronted cabinets. The lights are overhead fluorescents, and they're too bright—they press against his eyelids like a thumb, making him squint even as he tries to orient himself. A monitor on an articulated arm stands dark and dormant beside the table. Wires trail from somewhere beneath the sheet to a bank of machines he can't see without turning his head further.

He doesn't turn his head further.

Because he's starting to notice other things.

The sheet covering him is thin, papery, the kind that crinkles when he moves. It's draped over him from chest to mid-thigh, but he can feel air on his shoulders, his arms, his legs below the knee. Naked under the sheet. That's standard for a procedure, he knows that, he signed the consent forms, he knew they'd need access. But his shoulders feel different. Narrower. The air touches more of them than it should.

He looks down.

The sheet makes a tent where his chest used to be flat. Two tents. Small, rounded, distinctly female, pressing the paper up in a way that makes his stomach drop through the table and keep falling.

"No."

The word comes out cracked, dry, and—

He stops.

His hand flies to his throat. The motion is fast, reflexive, and his hand catches his attention halfway there—smaller than it should be, fingers longer and more slender, nails clean and shaped, the back of his hand smooth in a way his hands have never been smooth. No knuckle hair. No veins standing out. The skin is paler, softer, and his fingers press against his throat—his throat, which feels different under his touch. The cartilage is less prominent. The column of it narrower. His pulse flutters against his fingertips, rapid as a bird's heart, and the throat he's touching is a woman's throat.

His throat is a woman's throat.

The scream building in his chest doesn't have an exit yet. It lodges somewhere behind his sternum, a hot tight knot of denial that won't quite convert to sound. He opens his mouth to try again—to say something, anything, to prove this is wrong—and what comes out is a thin, reedy whimper that dies before it becomes a word.

A voice that is not his voice.

Higher. Softer. The instrument of it thinner, the resonance chamber of his chest smaller, the air moving through vocal cords that don't belong to him. He hears it and knows it's coming from his mouth and the denial in his chest cracks open and starts to leak.

He pushes himself up. The motion is clumsy, uncoordinated—his body doesn't have the same center of gravity, the same distribution of weight. His arms shake as he braces them against the table, and the sheet slides down to pool in his lap, and he sees himself.

His chest is wrong. Breasts, small and high and soft, the nipples pale pink against skin that's too smooth, too hairless, too pale. His collarbones are more delicate, his shoulders narrower, his arms slimmer. He looks down along the length of his body and sees a waist that curves in, hips that flare out, thighs that press together differently, the shadow between his legs—he can't see it clearly, can't bring himself to look directly, but the absence of familiar weight, the different topology of his own body, is a silence that screams.

He is a woman.

"No. No, no, no—"

The voice keeps breaking. Keeps coming out wrong. Each syllable is a fresh confirmation, a new cut. His hands— her hands, smaller, softer, trembling—press against his chest, palm over each breast, and the flesh gives under his touch, tender and real, and he makes a sound that is almost a sob.

"What did you do to me?"

The words are aimed at the only other person in the room.

Dr. Helena Vance stands at the foot of the exam table, ten feet away, a tablet held loose in one hand, her gray eyes tracking him with the calm of someone watching a reaction they've seen before. She hasn't moved. Hasn't spoken. Her auburn hair is pulled back in its severe bun, not a strand out of place. Her lab coat is pristine, the collar crisp, and she regards him the way she might regard a culture in a petri dish—interested, detached, waiting to see what the cells will do.

Her stillness is the worst thing about her.

"You're awake," she says. Her voice is measured, clinical, the same tone she used during the intake interview, the same tone she used when she explained the procedure would be painless and reversible. "That's good. The anesthesia window was estimated at forty-five minutes. You're within parameters."

"Parameters?" His voice cracks on the word, spiraling up into something almost shrill. "Look at me. Look at me. I'm—this isn't—" He gestures at his body, at the breasts, the curves, the wrongness of everything. "This wasn't the deal. The deal was—"

"The deal was that you would be enhanced," Dr. Vance says. She doesn't move. Doesn't even shift her weight. "And you have been. The phenotype expression is precisely within projected parameters. Increased symmetry. Refined secondary sexual characteristics. Optimized hormonal profile."

" Female secondary sexual characteristics." He's shaking now. The whole body trembles, fine and constant, and his voice wobbles with it. "You made me a—you turned me into a girl."

"Subjectively, yes. Objectively, the treatment achieved a 97.4% expression efficiency, which is above the expected baseline for this genetic pathway. The estradiol levels will stabilize over the next seventy-two hours, and the physical morphology is locked in. You are, biologically and functionally, female."

The words hit him like a physical blow. Each one a hammer. Estradiol. Morphology. Biologically and functionally female. The clinical precision of it, the way she says it like she's reading a report, like she didn't just do this to him.

"Change me back." His voice is raw. "Now. Change me back, right now, I'm not—I didn't sign up for this, I signed up to be—"

He chokes on the word. Handsome. Irresistible. The kind of guy girls flock to. That was the fantasy he'd sold himself on. That was the dream the glossy brochure in Dr. Vance's office had promised. Become the best version of yourself. Unlock your genetic potential.

He hadn't read the fine print.

"The treatment is not immediately reversible," Dr. Vance says. Her gray eyes don't blink. "The genetic rewrite has already propagated through your somatic cells. Reversing it would require a secondary treatment that hasn't been developed yet."

"Haven't developed it?" He's crying now. The tears come hot and sudden, streaming down his cheeks, and he can't stop them, can't even breathe properly, the sobs shaking his smaller frame in ways that feel alien. His shoulders hitch. His chest heaves. And the sound he makes—the sound of a woman crying—is the most humiliating thing he's ever heard come out of his own mouth. "You turned me into a girl and you don't even know how to turn me back?"

"The technology is iterative. Each treatment informs the next. You are—" She pauses. The first pause she's taken. Her eyes flicker, just briefly, something almost like guilt crossing her face before it smooths back into neutrality. "You are a successful proof of concept. The genetic pathways performed exactly as modeled."

" Proof of concept? " He's laughing now, a hysterical, broken sound that doesn't belong to his new voice any more than the crying did. "I'm a proof of concept? I'm a human being, you—you bitch, you didn't even tell me this could happen, you didn't give me a choice—"

"You signed the consent form."

"I signed a form that said I'd grow a few inches and get better bone structure and—" He stops. Presses his palms against his eyes. The heels of his hands are smaller, the pressure different, and the self-soothing gesture he's used his whole life feels wrong, doesn't work, because everything is wrong. "I want to talk to someone. A lawyer. My parents. Someone who isn't you."

"You can." Dr. Vance sets the tablet down on the counter. The movement is unhurried. Deliberate. She reaches into the pocket of her lab coat and pulls out a small vial, capped with a rubber stopper, filled with a milky fluid that catches the fluorescent light. She holds it loosely, not offering it, just holding it, her fingers wrapped around the glass. "But I'd recommend waiting until the initial hormonal cascade has finished settling."

"What cascade?" His voice is hoarse. "What are you talking about?"

She doesn't answer. She just watches him, the vial still in her hand, and her gray eyes are patient and knowing, and something cold trickles down Marcus's spine that has nothing to do with the exam table.

"What did you do to me?" he whispers. The tears are still wet on his cheeks. His voice is a woman's voice, and it shakes. "What else did you do?"

Dr. Vance's lips press together, a thin line. She doesn't answer. She just looks at him with those cool gray eyes, and the vial in her hand catches the light again, and Marcus feels something stir in his gut—a strange, hollow ache that has no name and no precedent and no place in the body of a man who woke up fifteen minutes ago expecting to be handsome.

A hunger.

He doesn't know what it wants yet.

But it's there. Waiting.

And the woman with the vial is watching him feel it for the first time. Her hand trembles slightly—barely visible, barely there—and then she steadies it, and her face goes smooth, and she stands at the foot of his table like a scientist waiting for her experiment to reach the next checkpoint.

Marcus's hand is still pressed to his throat. He can feel his pulse beating against his palm, fast and thready, and his voice, that wrong high voice, echoes in the sterile silence.

He can still hear it.

He thinks he'll never stop hearing it.
