Seventeen-year-old Mia Harper plans to spend her senior year invisible. After last spring's meltdown and a friendship breakup that still bruises like a fresh wound, she just wants quiet---no drama, no rumors, no attention. But then Luca Rivera walks back into town. Golden boy. Ex-best friend. Her almost-something... until he left without saying goodbye. Now he's taller, louder, annoyingly charming---and he seems determined to pull Mia back into the world she's spent months avoiding. But loving someone who once broke you is dangerous, and Mia knows better than anyone that the sun can warm you... or burn you. Still, the more she pushes him away, the closer he gets. And the closer he gets, the harder it becomes to remember why she ever let him go.
