Theo, a seventeen-year-old London schoolboy with a single mother, is desperate to track down the father who left them, whom he scarcely remembers. At school he discovers Greek mythology and the ancient story of Theseus, a fatherless son driven on a similar search. As Theo focuses on Theseus in a series of poems he composes, it becomes clear the two journeys echo each other in uncanny ways. Theseus must conquer his enemies--a psycho Cyclops, a tree-bending murderer, a monstrous pig--while Theo is tricked and double-crossed, confronting obstacles ranging from a search-agency scam artist to a depraved lawyer. Poet Joseph Coelho brilliantly interweaves the boys' stories, following them through dangers, horrors, and false successes, revealing that Theo must be as resourceful and strong as his mythical hero. In a unique twist, readers are asked to take a role in picking which option the heroes should pursue when facing choices on their path to manhood. The two alternating stories, along with stories from the Minotaur's perspective, fuse into one in a riveting climax, as the protagonists meet in the heart of the labyrinth.
