Goblins and Grimalkin — Joe M. McDermott

Goblins sneak. Goblins steal. Goblins stay hidden from the land of giants and grimalkin and trolls and elves. They live in old juniper trees hiding their villages and royal buildings in the deep forest. Rambol goblin is determined to be the greatest sneak thief of all goblin-kind, not a tree-sniffer like his parents. He wants his statue forever on display in the Goblin Hall of Greatness and Their Great Goings On, and that means he must do an exceptional act of thievery, like taking the tooth of a living troll. The path is perilous, and the danger vast. But, he does not go alone into the grimalkin kingdoms, where giants live among the roads and buildings.
