Last Stand of Dead Men by Derek Landy

He's dead. She's deadly. The bad guys don't stand a chance. The eighth book in the bestselling Skulduggery Pleasant series. Two wars rage. One is a war between Sanctuaries - a war of loyalty and betrayal and last, desperate stands. The other is a war within Valkyrie Cain's own soul. If she loses, Darquesse will rise. And the world will burn. `A thoroughly satisfying blend of humour, magic and adventure' Rick Riordan, author of the Percy Jackson series
