Abhorsen(2003)

Garth Nix

ORANNIS THE DESTROYER HAS BEEN FREED

AND ONLY LIRAEL, newly come into her inheritance as the Abhorsen-in-Waiting, has any chance of stopping it. She and her companions --- Sam, the Disreputable Dog, and Mogget --- have to take that chance. If Orannis's unspeakable powers are unleashed, it will mean the end of all Life. With the help of her companions and a vision from the Clayr to guide her, Lirael must search in both Life and Death for some means to defeat the Destroyer --- before it is too late. . . .
