Popular fitness influencer Gemma has transformed herself from a Before into an After, complete with washboard abs, thriving business, and gorgeous husband. But social media can be deceiving. Offline, the cutthroat world of bikini bodybuilding may just eat her alive. That’s if she’s not first devoured by the secret nemesis that lurks beneath her polished surface, waiting to destroy her. Software engineer Ashley is fat and frustrated. Frustrated with failed diets. With a world that wants her to shrink. With biased doctors, online trolls, and even her own mother. Until Ashley falls in with a mysterious and radical sect of Fat Activists who are fighting back … by any means necessary. She’s never felt so alive, so full of purpose. She’ll do whatever it takes to ride this high, destroy Diet Culture, and win the approval of her charismatic leader. Gemma and Ashley are on a collision course headed for the Olympia, the bodybuilding competition where futures are made. And lost. When Gemma’s toughest rival turns up dead, and more fitness girls fall like dominoes, it’s beginning to look like the body image war has gone too far. With breakneck pace and keen insights, takes a hard look at social media, the $70 billion diet industry, and the war on women’s bodies—the wars we wage with each other, and with ourselves.
