"On the evening of Sofia Claremont's seventeenth birthday, she is sucked into a nightmare from which she cannot wake. A quiet evening walk along a beach brings her face to face with a dangerous pale creature that craves much more than her blood. She is kidnapped to an island where the sun is eternally forbidden to shine. An island uncharted by any map and ruled by the most powerful vampire coven on the planet.
