Broken Beautiful Hearts by Kami Garcia

Before, Peyton was a star soccer player with the perfect boyfriend, Reed. Now, she has a torn knee ligament, a scholarship on the line, and a shattered sense of self. No one believes Reed pushed her, causing her injury, and Peyton just wants to leave the trauma behind. Living with her uncle and twin cousins in their small, football-obsessed town seems like a great escape plan.

There, Peyton meets Owen—high school classmate and local MMA fighter. Though Owen is charming and gentle, Peyton is determined to repress her growing attraction. But when her old and new life collide, Peyton must reclaim the truth of her past in order to save her future.
