Lucy Dungston has woken up to find all the grown-ups in her town have disappeared. <br/> <br/>Lucy's friends are thrilled there are no more grown-ups. They're running wild! They're building roads of trampolines, and eating cereal for every meal. <br/> <br/>But Lucy wants her mum back, and nothing is going to stop her. <br/> <br/>Even if it means having to venture into the strange, upside-down world of the mysterious monsters under her bed... <br/> <br/>And the upside-down world isn't the most hygienic of places . . . <br/> <br/>Tom Fletcher's bestselling story is packed with amazing illustrations by the disgustingly talented Shane Devries. It's the perfect spooky (and slightly gross) tale for Halloween!
