Tenth-generation monster-hunter Grace has a unique way of bumping off monsters. She and her sister run a bakery, Cake Hunters, where they make fabulous creations full of a special exploding baking powder that will get rid of any troublesome monster! And now Grace has a new and unlikely partner in crime - 360-year-old cyclops Mr Harris. They have a new and perilous mission from the Secret Service - to rid the city of a pesky Bottom-Biter who is causing havoc. If only Mr Harris would stop just eating the monsters and honing his advanced patisserie skills in Grace's bakery, what a team they'll make!
