We live in the world of Ordinary Time. Ordinary things happen in ordinary ways to ordinary people ... but Spryce Winthrow is far from ordinary. Spryce is special-an attribute he is happy to have when he finds himself lost and wandering in the secret world of the Underground. There, he meets Ibrahm Firebrace; very quickly, Spryce's ordinary life becomes extraordinary.
Firebrace is the powerful, legendary leader of the hounds. For years, the hounds have fought back against the evil Wretchens and their army of servant Sleapers. Unluckily, though, they now find themselves one soldier short. Spryce could stand in, but he must decide if he is willing to risk his life for the Underground. When secrets begin to surface, though, his decision is made.
As Spryce prepares to fight, he comes to realize there is more to this battle than meets the eye. The hounds search for the lost city of Citium to bring an end to the war, but the Wretchens are up to something-something that could prove the end of Spryce and his world. Is it possible that a battle in the Underground could cause chaos in Ordinary Time? If so, is it possible for Spryce to stop impending doom, before it's too late?
