Kalen Vey has spent two years running from the kingdom that condemned him for raising the dead. Then the Grey Kestrels-the regiment he built-find him at Ilyr Pass with an army of corpses at his command and an impossible message: Edrath needs him.
Across the kingdom, graves are opening. Every soldier killed fighting the Hollow Host rises to join it. Behind the dead stands Talia Rhen, the healer Kalen once loved, armed with an ancient system that can preserve a human mind beyond death.
Talia calls it mercy. The Crown calls it salvation. Kalen knows what it becomes when no one is allowed to refuse.
To stop a second Hollowing, he must return to the battlefield where fifteen thousand soldiers were sacrificed to bury the truth-and decide whether the power to save a person can ever justify possessing them.
