An arcane horror emerges from battle and blood.

To stop it, Lily must risk becoming everything she fears.
In a Europe devastated by four years of war, a platoon of elite Italian soldiers is horrifically and mysteriously slaughtered. Strangford’s arcane ability can uncover the truth behind the massacre, but a violent fate stalks him from the trenches. It’s up to Lily to change its course.
To save the man she loves, she must gather allies scattered by war, grief and betrayal. Her quest will take her from a landscape of wire and guns to ice-dimmed caverns and an ancient forest haunted by a threat far more terrible than mere wolves. 
For there is more at stake than Strangford’s life, or even the outcome of the war. The future itself is threatened by monsters from the far side of time, born from the bloodsoaked work of Lily’s worst enemy. Everything hinges on opening herself to the darkest potential of a power that could tear her apart—and on who is left to pull her back together again.
