Here Be Monsters! by Alan Snow 529 p.

Hang on as you embark on a rollicking, riotous, well-illustrated tale of the fight between good and evil among the odd creatures in the city of Ratbridge. Plucky young Arthur and his friends, the pirates, rats, and boxtrolls, discover a horrible plot by Snatcher, the rotten head of the Cheese Guild, to take over the town with a giant monster.
