After two long years, Mariah makes good on her promise to return to the forest, where she and her dog Willow find that things have become far more complicated for their friends, Pauly Wells and Rio. The mysterious girl named Beth holds the key to their reunion, which has been made all the more difficult by an ongoing power struggle between Mr. Tout and Pauly's twin brother, Owen. Caught in an endless marsh, they'll need more than their combined wits to escape the dangers coming at them from every direction.
