When twelve-year-old Garland Maddigan asks Timon and Eden where they have come from, she is overwhelmed by their answer: the future.
In a post-apocalyptic time, Garland's family's traveling circus troop, Maddigan's Fantasia, leaves the city of Solis once a year to perform and earn a living. However, this year Solis has given the Fantasia the crucial task of obtaining a new solar converter, the only power source in Solis, because the old one is failing.
Misfortune finds the Fantasia in their travels, and Garland's father dies in an attack by Road Rats. Then suddenly two mysterious boys, Timon and Eden, appear with their baby sister, claiming to be from the future -- a world in which the Fantasia has failed in its mission and the evil Nennog has taken power. The boys have come to help the Fantasia, but danger has followed them across time. Can the Fantasia protect Timon and Eden, and succeed in their quest to save their world?
