National Book Award winner Pete Hautman weaves several diverging time streams into one satisfying masterwork in this stunning and revelatory series finale. In a far distant future, Tucker Feye and the inscrutable Lia find themselves atop a crumbling pyramid in an abandoned city. In present-day Hopewell, Tucker’s uncle Kosh faces armed resistance and painful memories as he attempts to help a terrorized woman named Emma, who is being held captive by a violent man. And on a train platform in 1997, a seventeen-year-old Kosh is given an instruction that will change his life, and the lives of others, forever. Tucker, Lia, and Kosh must evade the pursuit of maggot-like Timesweeps, battle Master Gheen’s cult of Lambs, all while they puzzle out the enigmatic Boggsians as they search for one another and the secrets of the diskos.
