About the BookAbhorsen is the third book in the Old Kingdom series, written by Garth Nix. It follows on from the second book Lirael, and follows the lives of Lirael, Sam, Mogget (a demon of sorts- in the shape of an albino man/cat) and the Disreputable Dog (who is also some sort of ancient creature). Both animals can talk, and Mogget adds the sarcasm to the story.
Lirael and Sam are heading to the Red Lake, a place of great evil, in the Old Kingdom. They are persued by the dead and hunted by a Necromancer (raiser of the dead) called Hedge. They have to rescue Sam's friend Nick and stop Hedge from unearthing a great evil upon the land.
