Arthur Penhaligon is supposed to be in bed - after all, it's only twelve hours since he saved the world. But there's no time to rest. Grim Tuesday has laid claim to the Lower House and the First Key, and now his misshapen servants are repossessing Arthur's world and plunging it into financial disaster.

With companions old and new, Arthur embarks on a heart-stopping adventure that will take him from the dismal Pit of the Far Reaches, all the way to the heart of a sun and back. Garth Nix is the best-selling author of Sabriel, Lirael and Abhorsen.
