Selene, a formidable vampire death dealer, finds herself in the crossfire of a brutal war between the vampire and the lycan clans. Despite her illustrious history as one of her kind's most powerful warriors, both sides have turned against her as they pursue her blood for its unique properties – blood that can bestow enhanced strength and invulnerability. As the new lycan leader, Marius, aggressively pushes his werewolf clan's advantage, Selene must confront betrayals and seek out allies in unexpected places to protect herself and the vampire race from certain destruction.

Struggling to cope with the immense losses she has endured, Selene sets out on a quest for vengeance and redemption. Her quest leads her to seek training from an elite vampire coven unyielding in their rules and ways. Meanwhile, the lycan threat grows more powerful with each passing day as they close in on the vampires. With a deepening conflict ramping up on both sides, necessary alliances are formed, and Selene, with the help of her old ally David and his father Thomas, must brave the intense enmity that surrounds her, navigating a maze of conspiracies, treachery, and savage warfare to turn the tide in the immortals’ favor.
