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
