Sofia has just finished university and ended a troubled relationship when she attends a lecture about a New Age movement, Via Terra. Its leader is Franz Oswald, young, good-looking, urbane and mesmerizing.

When Sofia meets Franz Oswald, the handsome, charming leader of a mysterious New Age movement, she's dazzled and intrigued. Visiting his headquarters on Fog Island, Sofia's struck by the beautiful mansion overlooking the sea, the gardens, the sense of peace and the purposefulness of the people who live there. And she can't ignore the attraction she feels for Franz.

So she agrees to stay, just for a while. But as summer gives way to winter, and the dense fog from which the island draws its name sets in, it becomes clear that Franz rules the island with an iron fist. No phones or computers are allowed. Contact with the mainland is severed. Electric fences surround the grounds. And Sofia begins to realize how very alone she is and that no one ever leaves Fog Island...

Flowers in the Attic meets The Girls, Fog Island is a gripping combination of fear, sexual tension and lethal fascination.
