This was a different sort of tale and I still haven't decided whether I like it or not. Twig is an orphan raised by wood trolls. The catch: he doesn't know he's not a wood troll until he's a preteen and is told he has to find his own kind to live with (the sky pirates--humans). Along the way he meets the terrible inhabitants of the deep woods. The end is hokey and predictable, but the book was pretty adventurous in itself.
