A land of death and shadow where only the strongest survive. Yet that is where Caim must go to follow the mystery at the heart of his life. Armed only with his knives and his companions, he plunges into a world of eternal night where the sun is never seen and almost every hand is turned against him.

Only Kit, spectral vision and often unreliable accomplice, will stand by Caim in his darkest hour. But how much can he rely on her, when he can't even fulfil her greatest wish? Kit is in love with her companion, and he may not even know it. And even a Fae's tolerance will only last for so long ...

Caim has buried his father's sword and found some measure of peace, but deep in the north an unfathomable power lays waiting. To succeed on this mission, Caim will have to more than just survive. He must face the Shadow's Master.
