After years of waiting, the Blood Law is at last avenged. Lycan Alpha Lucien Mondragon takes revenge on his brother, Rafael. Lucien is poised to slay Rafael's life mate, the Lycan/Slayer half-breed Falon- but cannot complete the kill. For Falon's mystical powers and fiery nature awaken a heart Lucien thought long dead. Instead of ending her life, Lucien defiantly marks Falon as his own, tormenting his brother to insanity and spurning Rafael's blood thirst for his own revenge.

Though terrified by the savage Lucien, Falon finds herself inexplicably drawn to his primal rage and strength by a desire she cannot resist. Torn between the true love she has for Rafael and the burning hunger she holds for Lucien, Falon knows that the will of her heart will lead her to her destined life mate. But it may also doom the Alpha brothers-and the Lycan race-to extinction...
