Branded a powerless half-breed because she cannot shift, Ella is betrayed by her werewolf clan and thrown into the Eternal Night Abyss as a sacrifice to the vampires. Instead of dying, she awakens a forbidden bloodline—part ancient Moon Wolf, part Firstborn Vampire—and forms a dangerous alliance with Karen, the cursed and ruthless Vampire King. As Ella masters her dark new powers, she uncovers the truth about her imprisoned mother and the prophecy that has haunted Leon, the tyrannical Alpha King, for centuries. What begins as a quest for revenge grows into a rebellion uniting vampires, outcast wolves, and oppressed clans. With war closing in and love challenging everything she believes, Ella must choose whether to become the monster her enemies fear—or the queen who can end a thousand years of hatred and build a world where blood no longer determines destiny.
