In the French Caribbean, there is an island protected by a bountiful reef. Its sandy beach is pristine, and its shallow lagoon's waters are warm and welcoming. It's known to but a few, and only the greedy will give up its location.

Sabine and the Callen brothers, fresh from a disappointing trip to Guadeloupe, in search of the George Wall Pirate treasure, travel to the island to follow up on a clue buried in the maritime records. The moment their luxury sport yacht anchors, Sabine is overwhelmed with a sense of evil.

The Martins are looking forward to enjoying a few childfree days when Sabine calls Mia. She needs advice. Mia hears the panic in Sabine's voice and seeks out answers. But the more she looks into the problem, the more it becomes apparent that Sabine is in mortal danger if she stays where she is.

Mia and Ted put together a small team to go extract Sabine and convince the Callens to leave the island. But they arrive too late, and now, not only is Sabine in danger, but so is the whole human race.

Set sail with Mia, Murphy, and PEEPs as they set out to fight what has Risen in the French Caribbean. Risen is the 22nd book of The Haunted Series.
