Cookie’s world is turned upside down when her best friend moves away to Solihull and her family’s “no-pet” rule is enforced—until Cookie finds a way around it. She visits a pet shop and falls in love with a kitten she names Bluey. But disaster strikes: the most annoying boy in the world buys Bluey, renames her Nigel, and ends up moving in next door! As if that weren’t enough, Cookie is also determined to represent her school on a TV quiz show Brainbusters, which means she must win the Year 5 science project first. But keeping her cool, staying out of trouble, and staying focused is easier said than done when Cookie’s natural enthusiasm keeps getting her into scrapes.
