For Sera Anderson, the Olympics is the reason for everything: it’s why she trains thirty hours a week, starves off her period, and pops Advil like Tic Tacs. For her mother, it's a means to achieve the glory she never had. It's why she rises before dawn to drive Sera to practice. And why the family scrimps, saves, and fractures. It’s why, when her best friend and fellow elite gymnast reports their doctor to the authority who selects the Olympic Team, Sera denies all that she knows about his treatments. Their friendship shatters. But Sera protected her dream—didn’t she? Sera doubles down, enlisting an abusive coach, numbing torn muscles, turning to Adderall for extra energy and focus, and then upping her dose. Soon, she isn’t training for the love of the sport. She’s training to make her disloyalty worthwhile. No matter the cost.
