Deja Hadley is the quiet top student-rules, routines, and a five-year plan. She's invisible to most people, and that's how she likes it. Until she's assigned a senior project partner: Lux Barrett, the school's golden-haired heartbreaker. Star athlete, serial flirt, never seen with the same girl twice. He doesn't take school seriously-and definitely not girls like Deja . Forced to work together, their partnership starts rocky. Lux is distracted and unreliable. Deja is cold and dismissive. But as their project requires real collaboration, their walls start to crack. She challenges him. He listens. She starts to laugh around him. He starts to show up-early, even. Rumors spread. People talk. Deja friends warn her he's just playing with her. Lux's circle mocks him for "catching feelings." But behind library meetings and late-night texts, something real is building. Then Lux does what he always does-pulls away the second things get real. Now Deja has to decide if she'll chase the boy everyone says will never change... or make him prove, for the first time in his life, that he can.
