Where one journey ends . . . another begins.
Watching a psychopath suck the life from your father is one way to create a vengeful daughter—and Lyra Roux knows firsthand about revenge. More than just a skilled assassin, she’s one of three fated queens, destined to restore peace to the Kresova vampires.
Thanks to Lyra’s assistance, Queen Morana is weakened and no longer protected by ancient forces, but the fight to dethrone the evil queen is more dangerous than ever. Back home in Ireland, Lyra is faced with a choice—go against her father and her coven’s customs, or follow her fate, even if that means one of her consorts is a sexy-as-hell werewolf.
Morana’s plans aren’t as straightforward as they thought. With those Lyra loves at risk, she will have to bind vampires, werewolves, and even the Fae. For this half-blood queen, this war isn’t just business—it’s personal.
But a vampire queen’s harem can’t begin with a sexy werewolf, can it?
