The FINAL shocking, heart-wrenching book in the jaw-droppingly stupendous Skulduggery Pleasant series. The War of the Sanctuaries has been won, but it was not without its casualties. Following the loss of Valkyrie Cain, Skulduggery Pleasant must use any and all means to track down and stop Darquesse before she turns the world into a charred, lifeless cinder.

Derek Landy is the author of the internationally bestselling Skulduggery Pleasant series. He doesn't like to brag about all the awards he's won, such as the Irish Book of the Decade, or the Red House in the UK, or all the other awards that he humbly displays on his mantelpiece. He is also far too modest to mention things like the first book being a Publisher's Weekly Best Book of the Year, but would like to extend an invitation to Oprah to pop around one day for tea, in thanks for selecting his book for the Oprah's Book Club Kids Reading List. Derek plays too many video games, reads too many comics, and watches too many movies. He lives in Ireland with too many cats and too many dogs. Occasionally he talks to real people, but only when he absolutely has to.
