A Guide to Winning the Vampire King's Heart

Twenty-two young women wake inside Blood Moon Castle, a fortress pulled from the ocean and left hanging in the sky. Anderson, the Vampire King, gives them seven days to endure brutal trials, and only the survivors can leave. Diana, the one ordinary girl among them, is handed an unlikely chance by a mysterious system: make the Vampire King fall for her, or die trying. But the closer she gets to him, the more their bond changes from strategy to something real. What starts as a fight for survival turns into a dangerous love, until Diana learns Anderson is trapped by a deadly curse—and only she can break it.
