This is the epic, never-before-told story of the Super Zeroes' first ever active mission as real-life superheroes! A brilliant new mini-adventure in the bestselling, award-winning Kid Normal series, exclusively for World Book Day 2020. Join Murph Cooper and the Super Zeroes as they team up with wonderful school librarian and secret superhero Mrs Fletcher (whose special power is that her head can turn into a foghorn) to foil a dastardly, 1000-decibel plot. When Mrs Fletcher's friend Margaret disappears from her duties as town librarian, it's clear that there's something strange afoot. A librarian never deserts their post! Plus the library has suddenly started hosting a whole host of ludicrously loud events. Cow choirs, pneumatic drill masterclasses, stamping competitions ... could a dastardly criminal be using the library to cover up a crime of epic proportions? It's up to Murph, Mary, Hilda, Billy and Nellie to get to the bottom of this mega-loud mystery.
