The coming of the Blood Moon will lead two Lycan packs into war, spur two rival brothers into conflict, and spark an act of vengeance so evil that its effects will be felt for generations. One woman stands at the center of it all… A volatile mix of both Lycan and Slayer, half-breed Falon is Alpha female of her pack, marked by both Lucien and Rafael-rival Alpha brothers that share equal hold on her heart. But when Falon's mysterious past completely unravels, it is revealed she is the daughter of the Master Slayer who murdered Lucien and Rafael's parents. The revelation throws her relationship with both brothers into chaos. Falon begs them not to condemn her for her father's deeds. She realizes before her Alpha mates that they are destined to be one and pleads with them to accept the unusual triangle. If the brothers accept her as their mate then the Blood Law of an eye for an eye would be null and void. But if Lucien and Rafael cannot overcome their pride and accept their fate, the annihilation of the Lycan race waits within the shadow of the Blood Moon…
