Ray Carpenter is a glass-half-full control freak who just wants the world to make sense. When the Warp suddenly descends on humanity, though, bizarre mental illnesses strike adults all over the globe and throw his life into chaos. Ray's mother becomes convinced that her right hand is a parasite, his wife is gripped by the notion that she's a corpse, and Ray himself is haunted by delusions that his loved ones are imposters.

As the adults grapple with madness, grotesque transformations alter the children. Ray's son develops strange bumps on his skin and an unsettling sixth sense, while his behavior grows increasingly incomprehensible and ever-more disturbing.

Ray struggles to hold onto his sanity and his family-but as the Warp twists reality, it may change them all into monsters.
