Jeb wakes up on the toilet after sixty-three years, to discover that humanity has been torn apart by war and unlikely science. He must brave the zombie hordes, the dirtbag biker gangs, the radioactive wastelands and space itself, to reach the remnants of civilisation, sheltering on an orbital habitat. There he discovers a pseudo-religious cult in thrall to a despotic children's author, who must be exploded in order to reset time and save Jeb's friends, career and love life.
