It figures. Just when Bradfordian bookshop clerk, Toby Dexter, finally works up the nerve to talk to his secret crush, she darts into an open door. Toby follows, and in that second, everything changes. Though it still looks like Bradford-on-Avon, the town's suddenly chatty ATM and river mermaids are the first clues that something is quite out of place-namely, Toby. The moment he stepped through that door, Toby entered the magical parallel world of Mysterie.

Our ordinary dimension-the one Toby knew as Bradford-on-Avon-is actually Veritie, a mere shadow of its alter ego, Mysterie, where magic and myth, gods and monsters, living legends and walking nightmares reign. And Toby isn't the only recent arrival. A cunning and vicious demon-The Serpent's Son-has returned to Mysterie, accompanied by a malevolent new ally, intent on bringing down both dimensions.

Toby can remain mortal, return to Veritie, and try to convince himself that he had a bad pint of bitter that night. Or he can stay in Mysterie, join forces with his new friends Leo Morn and his Brother Under The Hill, and try to stop The Serpent's Son. The choices Toby makes will have dramatic consequences for both worlds. It may not be the first time Mysterie's wars have spilled over into our reality, but if Toby fails, it could be the last.

Simon R. Green, New York Times bestselling author of the Deathstalker series and the Nightside series, brings his trademark wit and inventiveness to his beloved hometown of Bradford-on-Avon, in this charming standalone urban fantasy novel.
