Ariel is afraid of her own mind. She already feels like she is too big, too queer, too rough to live up to her parents' exacting expectations, or to fit into what the world expects of a "good girl." And as violent fantasies she can't control take over every aspect of her life, she is convinced something much deeper is wrong with her. Ever since her older sister escaped to college, Ariel isn't sure if her careful rituals and practiced distance will be enough to keep those around her safe anymore.

Then a summer job at a carnival brings new friends into Ariel's fractured world, and she finds herself questioning her desire to keep everyone out--of her head and her heart. But if they knew what she was really thinking, they would run in the other direction--right? Instead, with help and support, Ariel discovers a future where she can be at home in her mind and body, and for the first time learns there's a name for what she struggles with--Obsessive Compulsive Disorder--and that she's not broken, and not alone.
