Y/N is pulled into a hidden dimension ruled by vampires after her friend Brianna brings her into a world she was never supposed to discover. When the difference in time between dimensions leaves Y/N trapped, she must learn to survive in a royal vampire castle. There, she meets Alexander—the arrogant, sarcastic, stubborn prince and future king. What begins as constant arguing and playful rivalry slowly becomes friendship, trust, and something neither of them expected. But Alexander is already promised to another woman, and the castle holds secrets far darker than Y/N could have imagined. After a mysterious attack leaves Y/N fighting for her life, she becomes a vampire herself. As she learns to control her new powers, she and Alexander discover that their connection is more than love—they are soulmates. Meanwhile, Alexander’s family is hiding the truth about his biological father, his mother’s murder, and the forbidden West Wing that has remained sealed for years. The closer Y/N gets to Alexander, the closer she gets to a secret that could change everything. And perhaps her arrival in the vampire world was never an accident.
