Middle school hasn't been going well for Colin. His teenage sister teases him mercilessly, his autistic brother lashes out at him, and he has a crush on his best friend, Andy. But after the tragic night when his father commits suicide, none of that matters. Diane, his mother, seeks solace in therapy. Colin is awash in guilt, and casts about for someone to confide in: first his estranged grandfather, then a predatory science teacher. But nothing helps as much as the strange writing his father kept in a series of notebooks locked in his study.
