The Ironwood Tree by Tony DiTerlizzi, Holly Black

4.0

Mallory is snatched by some goblins and her brothers go after and try to rescue her. They meet the king who has a dream of conquering the world and re-creating it in metal. Towards the end of the book Mulgarath shows up - he's got his hands on "the Fieldguide" - and destroy the goblins. The ending is a real cliff-hanger.
