A Fortress of Grey Ice — J.V. Jones

BOUND BY DESTINY

Ash March knew Raif Sevrance was special from the moment he helped rescue her from the tyranny of her foster father in the city of Spire Vanis. Like her, Raif was an outcast. Though from different worlds, he from the clanholds, she from the fortress city, their lives were somehow entwined by fate and by the need of the cold, dark north of their world. It has been a thousand years since the dreaded Endlords have tried to breach the boundary between the living and the dead, but now the forces that hold back the damned souls of the dead have weakened; new heroes must emerge to combat this terrible threat.
Raif, wrongly accused and cast out of his clan by the treachery of their new headsman. Ash, raised as a foundling, is a warrior sacred to the Sull, an ancient race who once ruled the north. But raised in isolation, she must learn and accept the power and responsibility of her heritage.

As Ash learns of the role she must fulfill, Raifs task looms dark and desperate: he must journey through the nightmare realm of the desolate Want, where even the Sull fear to tread. For deep within the Want is the Fortress of Grey Ice, and there he must heal the breach in the Blindwall that already threatens the world. Should he fail, not even Ash's powers can save them .. .
