The Monster in the Lake By Louie Stowell & Davide Ortu

Kit is a wizard.

The youngest wizard in the world, in fact. But her magic keeps going wrong, and all kinds of weird stuff has started happening – exploding fireballs, animals talking when they shouldn’t be, and a very strange new arrival in a nearby park. So Kit and her two best friends – along with their local librarian – set off to investigate, and to save the world… again.
