Libby Strout is no longer “America’s fattest teen,” but her biggest fear in returning to school for the first time since fifth grade is that her classmates won’t look past her weight. Nonetheless, she’s ready to leave the house where she’s been grieving her mother’s death, and embrace everything high school has to offer. Meanwhile, Jack Masselin’s devil-may-care attitude may seem effortless, but nobody knows how hard he has to work, because nobody knows about his face blindness—how, even among his closest friends, he feels as though he’s surrounded by strangers. That is, until a vicious prank lands Jack and Libby in the same counseling group, and they’re forced to see beyond each other’s masks.
