After escaping the Vampire dungeons beneath the blood club Nocturne, Fae royal Torren de Brinna petitions Sylvan for sanctuary, setting Sylvan and her allies on a collision course with Francesca, Viceregal of the Eastern Vampire seethe. In the midst of war, Torren finds her heart at risk from a young dominant Were, while Francesca's Vampire enforcer Michel draws one of Sylvan's trusted guards into a web of seduction and danger.

Hunted by human extremists, targeted by the Shadow Lords who fear her growing power, and beset by enemies masquerading as friends, Sylvan leads the Timberwolf Pack to war on two fronts as alliances shift and long-held beliefs are challenged.
