The ruler of the Fang Throne, Vespera, returns to reclaim the throne that was usurped. A hundred years ago, she saved three dying wolf pups; a hundred years later, Roran, Jax and Caedren become three Wolf Kings, as well as three blood locks that sustain her life. The deeper she loves, the faster she dies. Her old mentor Morcant reveals the truth of the curse, forcing her to choose between possession, sacrifice and freedom.
