Bea Garcia is using her art skills to tell readers all about her best friend ever - her dog, Sophie. Sophie can protect her from anything, even the Garcias monster neighbour, Bert. When Bea's teacher makes her visit Bert for a school assignment, Bea brings Sophie along for extra security. But even monsters have pets, and Bert has a terrible one: Big Kitty. When Big Kitty attacks, Sophie runs straight out the door - away from Bea! Bea searches the neighbourhood with her mum, and calls for Sophie up and down the street with her dad, but her dog is nowhere to be found. Will Bea's best friend ever come home again?
