Chun was offering additional support. Even some previously hostile faces showed grudging respect. But Marcus's eyes found Professor Whitmore across the crowd. The professor nodded once, an acknowledgement, an apology, and a promise all in one gesture.

The National Mathematics Olympiad would test Marcus' abilities against the best young mathematical minds in the country. But in many ways, the hardest test had already been passed. He'd proven that brilliance could emerge from public libraries and subsidized lunches, that talent could flourish despite prejudice, that mathematics truly was democratic. Now came the work of proving it on a national stage.

And Marcus Johnson, the boy who'd learned calculus by candle light when the electricity was cut off, was ready. The competition had been announced. The real work was about to begin.

The Johnson apartment sat on the fourth floor of a building where the elevator worked sporadically and the hallway lights flickered like dying stars. But inside unit 4B, a different kind of light burned bright. The desk lamp Marcus had bought at a thrift store. illuminating pages covered with mathematical symbols that danced like poetry across recycled paper.

It was 10:47 p.m. and Diane Johnson was still at the hospital working her second double shift this week. Marcus had made himself dinner, pasta with butter again, and settled into his evening routine, 3 hours of Olympiad preparation after completing his regular homework in 45 minutes. The apartment was small enough that he could see everything from his desk.

The kitchen where his mother had taught him fractions using measuring cups. The couch where they'd cuddle and watch Khan Academy videos together when he was younger. The wall where she taped his first perfect math test with a note, "My brilliant boy." Marcus worked through problem sets he downloaded from the International Mathematical Olympiad archives. His solution sprawled across notebooks bought at dollar stores.

Each page precious, each proof a small victory against circumstance. A soft knock interrupted his concentration. Too soft for too late for neighbor. Marcus opened the door to find his mother still in her scrubs holding a small box.

Mom, I thought you had until midnight. Traded shifts with Patricia, Diane said, entering and setting down the box. Couldn't miss this day. My baby got selected for the national competition.

She pulled him into a hug that smelled of hospital disinfectant and exhaustion and love. "Marcus felt tears prick his eyes, but blinked them back. His mother had enough to worry about without adding his emotions to the list. "I brought something," she said, opening the box to reveal a graphing calculator, not new, but a high-end model.

"Found it at the pawn shop. The owner said it works perfectly. Just has some scratches." "Mom, we can't afford." Hush. You're going to the Olympics.

Olympiad. Marcus corrected gently. And you're going to have the right tools. Even if I have to work extra shifts.

Marcus turned the calculator over in his hands. Throat tight. He knew exactly how many hours of work this represented. How many meals his mother would skip to make the budget balance.
