Sequel: Tears of frost.

In the ancient river kingdom, touch is a battlefield, bodies the instruments of war. Seventeen-year-old Mia Rose has pledged her life to hunting Gwyrach: women who can manipulate flesh, bones, breath, and blood. Not women. Demons. The same demons who killed her mother without a single scratch. But when Mia's father suddenly announces her marriage to the prince, she is forced to trade in her knives and trousers for a sumptuous silk gown. Only after the wedding goes disastrously wrong does she discover she has dark, forbidden magic--the very magic she has sworn to destroy.
