Beyond the Deepwoods: The Edge Chronicles, Book 4

Young Twig lives in the Deepwoods, among the Woodtrolls, but he isn't one of them. In a brave attempt to find out where he belongs, Twig wanders into the mysterious, fascinating, and sometimes hazardous world beyond the Deepwoods. In his travels he encounters myriad peculiar creatures, like his wise guardian, the Caterbird; the Slaughterers, a peaceful race who butcher animals for their livelihood; and the vicious, bile-swilling Rotsucker. Always mindful of the Gloamglozer, whose presence haunts the thoughts of all the inhabitants of The Edge, Twig pursues his quest until he discovers his roots, not among the trees, but in the skies. With his new allies, the Sky Pirates, Twig prepares to embark on his next adventure.
