The Devil You Know (Felix Castor, 1)

Author of The Girl With All the Gifts Mike Carey presents the first book in his hip supernatural thriller series featuring freelance exorcist Felix Castor.

Felix Castor is a freelance exorcist, and London is his stomping ground. It may seem like a good ghostbuster can charge what he likes and enjoy a hell of a lifestyle, but there's a risk: sooner or later he's going to take on a spirit that's too strong for him.

When Castor accepts a seemingly simple ghost-hunting case at a museum in the shadowy heart of London, what should have been a perfectly straightforward exorcism is rapidly turning into the Who Can Kill Castor First Show, with demons and ghosts all keen to claim the big prize.
But that's business as usual: Castor knows how to deal with the dead. It's the living who piss him off. . ..
