Mud-splattered, sweat-stained, and perpetually on the brink of a crash, fifteen-year-old mountain bike racer Maryn O'Brien's dream is to make it to the Olympics. She trains hard and races harder, all while juggling school and her many other responsibilities. It's not easy, but it's doable-until her racing coach suddenly gets suspended just days before the most important race of the season. Now Maryn faces a serious decision. She has two secrets: one that could save Coach's career, another that could ruin her racing dreams...and she can't share one without telling the other. As Maryn races for the first time without her beloved coach's support, she battles not just her competition, but her conscience, too. Will she find the strength to win against both and redeem herself?
