In a disintegrating and lawless near-future, a young man journeys north to a mysterious island owned by one of the world's wealthiest men—and finds an entire new civilization waiting for him.

Ben is a painter from the crowded, turbulent city. For six months his fiancée, Cara, has been working on the remote island of Sanctuary Rock, the private estate of millionaire philanthropist Sir John Pemberley. Now she has decided to break off their engagement and stay there for good.

Ben travels to the island to try and win Cara back. After an arduous journey, he finds himself compelled to stay. But as Ben begins to traverse Pemberley's kingdom, he begins to uncover the truth of the apparently perfect society the enigmatic Sir John is building. Is Sanctuary Rock truly a second Eden, as he claims—or a previously undiscovered level of hell?
