Will, a musically gifted teen, is making his mark in a semiprofessional Chicago band. He is saddled with an abusive older brother who torments him and who, despite bottomless remorse, continues to commit stupid acts and crimes that create ongoing chaos and challenges for his family. Writing in a journal of sorts, Will tells his story in colloquial language, describing his futile crush on Amanda and the outrageous behavior of the adult band members who create a cult following as Kiss Forever, which both memorializes and satirizes the infamous band Kiss.
