Wildwood

All the wild places--forest and sea, mountain and plain--each have their own guardian to look after their lands and keep their humans safe. Among the greatest of these is the guardian of the vast Oakensea, but unlike his fellows, the forest lord hasn't been seen in generations, leaving his shrines deserted at the changing of the seasons. He's a ghost, and his villagers wait for the day he abandons them entirely, whether by falling to dark magic or dark creatures or by growing twisted, turning the immense forest into a sprawling, deadly tangletrack.

Sent by the king to replace a fallen ranger, Koster knows the forest's reputation. He's been inside a tangletrack when it turned, and he knows the dangers. But a chance meeting with a reveler at a Quarter Night's dance may change everything, for everyone in the Oakensea and for the Oakensea itself.
