Tribe of Mystics (The Guilty Banished, #2)

Primrose thought she escaped from the colony. She didn't get far. An accident sends her right back to the island, and back to her waking nightmare. Once again, she's stuck in the company of the intolerable Frederick Whitley.

Whitley and his soldiers are captured by the island Natives, who aren't as cruel as they seem. In fact, they seem to have respect for Primrose and her newly acquired abilities. Primrose can, after all, communicate with spirits.
