You can't outrun your own history.... Still trapped in Victorian London, FBI agent Chevie Savano is determined to help her friend, Riley, find his long-lost brother. But the WARP wormhole has other ideas.... Pulled two centuries into the past, Chevie and Riley find themselves in the village of Mandrake. Under siege from prowling monsters that have escaped from the wormhole, the village's only protector is the sinister Witchfinder - a man with a hidden past and deadly powers. With Chevie branded a witch and sentenced to be burned at the stake, can Riley thwart the Witchfinder's plans before he destroys them all?
"Colfer has the ability to make you laugh twice over: first in sheer subversive joy at the inventiveness of the writing, and again at the energy of the humour." (Sunday Times) "Readers mourning the end of the Artemis Fowl series can take heart: this first book in the time-bending WARP series is an all-out blast." (Publishers Weekly)
