"Rose and Lily Winters are twins, as close as the bond implies; they feel each other’s emotions, taste what the other is feeling. Like most young women, they’ve struggled with their bodies and food since childhood, and high school finds them turning to food—or not—to battle the waves of insecurity and the yearning for popularity. But their connection can be as destructive as it is supportive, a yin to yang. When Rose stops eating, Lily starts—consuming everything Rose won’t or can’t. Within a few years, Rose is about to mark her one-year anniversary in a rehabilitation facility for anorexics. Lily, her sole visitor, is the only thing tethering her to a normal life. But Lily is struggling, too. A kindergarten teacher, she dates abusive men, including a student’s married father, in search of the close yet complicated companionship she lost when she became separated from Rose. When Lily joins a cult diet group led by a social media faux feminist, whose eating plan consists of consuming questionable non-caloric foods, Rose senses that Lily needs her help. With her sister’s life in jeopardy, Rose must find a way to rescue her—and perhaps, save herself."-- [Goodreads]
