Chapter 1 The Water Bottle
The library at Ashford Prep smelled like old paper and lemon polish, and I had been sitting in the same chair for four hours when Sasha slid into the seat across from me. Her hair was wet from the rain, dark strands clinging to her cheeks, and she was holding two bottles of water.
"You looked thirsty," she said, setting one down next to my elbow. "I grabbed an extra."
I reached for it before I thought. That was the thing about Sasha — she had a way of making kindness look like nothing, like it cost her nothing, like she'd done it a thousand times before. Maybe she had. We'd been friends since freshman year, when she found me crying in the stairwell because I couldn't afford the lab fee for AP Biology and she'd paid it without asking. She never mentioned it after.
"Thanks," I said, and my fingers closed around the plastic.
And then the air in front of me flickered.
It was subtle at first, like heat rising off asphalt in July, a shimmer at the edge of my vision that I dismissed as exhaustion. But it didn't go away. It sharpened into something like text, floating six inches above Sasha's left shoulder, translucent and pale blue.
She was watching me, her chin propped on her hand, and for a second — just a second — her eyes dropped to the bottle in my grip.
The text sharpened.
If she drinks it, the swap happens in the testing center server during the exam upload. The proctor won't notice. He never does.
I didn't move. My hand stayed exactly where it was, wrapped around the bottle, and I felt my pulse do something strange and uneven in my throat.
"I'm not that thirsty," I said.
Sasha's smile didn't budge. "You've been here forever. You need to hydrate, Wren. You'll crash."
"I'll get something from the vending machine later."
"Those are stale." She leaned forward, and her voice dropped, softer. "Come on. You always do this — you take care of everyone except yourself."
I looked at her face, the face I knew better than my own. The small scar on her chin from a bike accident when she was nine. The way her left eyebrow arched higher than her right when she was pretending. The way she always, always knew what I needed before I did.
The text over her shoulder changed.
She practiced this. In the mirror this morning. Three times.
"I'm fine," I said, and I set the bottle down.
Sasha's smile held for exactly one more second, and then it did something I'd never seen before. It flickered. Just once, like a candle in a draft.
"Okay," she said, and pulled her textbook closer. "Suit yourself."
She didn't touch the bottle again. Neither did I. It sat there between us, sweating condensation onto a stack of index cards, and I stared at the periodic table on the wall and felt something cold settle in my chest that had nothing to do with the library's air conditioning.
Ashford Prep sat on thirty acres of manicured grounds an hour outside Savannah, and I had fought for every inch of my place there. My mother worked double shifts at a hospital forty miles away. My father was a name I didn't say out loud. I'd come to Ashford on a scholarship that covered tuition and nothing else — no meals, no books, no field trips. I'd worked in the library after hours and babysat faculty kids on weekends and written other students' essays for cash for two years before I stopped, because it felt like cheating and because I was terrified of getting caught.
Sasha Davenport was the opposite of me. Her family had given the school its new science wing. Her grandfather was on the board. She had a car and a credit card and a roommate who was also her cousin, and she'd never in her life had to wonder whether she could afford to eat lunch.
And for three years, she had been my best friend.
The text stayed with me. I saw it again that night, when I was alone in my dorm room, going over my notes for the chemistry midterm. It appeared at the edge of my desk lamp's glow, faint but legible.
The swap is keyed to a biometric signature. Her signature. It overrides the test taker's ID at upload.
I stared at it until it faded.
I told myself I was hallucinating. I told myself I was stressed. I told myself I hadn't slept more than five hours a night in two weeks, and that the human brain did strange things under pressure.
But I also didn't drink the water.
And when I walked into the testing center the next morning, I took a seat in the front row, three rows away from where Sasha and I usually sat together.
She noticed. She looked up from her pencil case, and her expression did something complicated — confusion, then understanding, then something else I couldn't name.
She didn't wave. Neither did I.
The exam began.
