The bad guys have won. With the end of everything just days away - and no longer able to rely on Valkyrie Cain - Skulduggery must make allies of enemies if he's going to stand any chance of saving what's left of the world. And just when things are looking their bleakest, they manage to get even worse, with Omen Darkly suddenly having to step up when his brother, the Chosen One, falls.

There's a lot going on. Most of it is bad. Sorry about that.
