Meet Lea Davis, a girl who nobody at school actually cares about, a girl with the brightest smile on all the time, a girl who can make you laugh without you saying anything, a girl who sees the world differently. But a smile can hide a lot, pain, grief, anger, deprivation, anxiety, regret and a whole lot of other emotions, Lea is a pro at hiding them from everyone and sometimes even her bff. Well until she bumps into someone mysterious, someone different, someone who can see through her smile and her whole life is turned upside down.
