Brother Wulf launches a new series set in the world of Joseph Delaney's Wardstone Chronicles. Sent by his monastery to spy on Spook Johnson, novice monk Brother Wulf expects to find a fraud — the Church has always taught him that Spooks are agents of evil, not protectors against it. Instead he discovers that the creatures Johnson battles are terrifyingly real, and that his own safety depends on trusting the very man he was sent to expose.
When Johnson is overwhelmed by a powerful adversary, Wulf has nowhere to turn but Chipenden, home of the young Spook Tom Ward. Tom's abilities both unsettle and reassure him, and the two are quickly drawn into a conspiracy that threatens Tom, his ally Alice, and everything they have fought to protect.
As a new and horrifying enemy rises, Wulf finds himself the only one positioned to stop it — a reluctant hero pulled far outside the world he thought he understood, continuing Delaney's dark fantasy universe for readers who grew up alongside The Last Apprentice.
