Lirael Daughter of the Clayr by Garth Nix (The Old Kingdom #2)

When the future is unclear, who holds the key to destiny? Sequel to the spellbinding, award-winning fantasy adventure, SABRIEL.

Lirael has never felt like a true daughter of the Clayr. Abandoned by her mother and ignorant of her father's identity, Lirael resembles no one else in her large, extended family living in the Clayr's Glacier. She doesn't even have the Sight - the ability to See into the present and possible futures - that is the very birthright of the Clayr.
Nonetheless, it is Lirael in whose hands the fate of the Old Kingdom lies. she must undertake a desperate mission under the growing shadow of an ancient evil - one that opposes the Royal Family, blocks the Sight of the Clayr, and threatens to break the very boundary between Life and Death itself. With only her faithful companion, the Disreputable Dog, to help her, Lirael must find the courage to seek her own hidden destiny.

Garth Nix draws readers deeper into the magical landscape of the Old Kingdom and weaves a spellbinding tale of discovery, destiny and danger.
