Moonlight Cage

Lynn Mu was just a bartender trying to survive when Adrian Kor, Commander of the Blood Council Guard, bit her by mistake. The blood bond activated. The rules are brutal: complete three ritual exchanges within thirty days or both hearts stop. She's the last demon hunter alive, three generations of her family slaughtered by vampires, and she only wants one thing—find her father's killer. He's the youngest commander in the Blood Council, hunting a traitor inside, and this bond gives his enemies ammunition. The bond can't be broken. Every seven days it forces them closer. On day seven they're locked in the same room, memories bleeding through—Lynn sees fragments of her father's death, Adrian discovers the ancient royal bloodline sealed inside her. They begin a dangerous alliance, hunting the traitor while testing each other's limits. But when her seal cracks, the entire Blood Council hears it: the King's Blood has returned.
