For six months his fiancée Cara has been living on the remote island of Sanctuary Rock, the property of millionaire philanthropist Sir John Pemberley. Now she has decided to break off their engagement and stay there for good. Ben resolves to travel to the island to win Cara back. But the journey there is a harsh and challenging one, and when he does arrive, a terrible shock awaits him. As Ben begins to find his way around Pemberley's perfect island, he knows he must also discover - what has made Cara so determined to throw her old life away? And is Sanctuary Rock truly a second Eden, as the mysterious Sir John claims - or a prospect of hell?
