The Monster in the Lake -Louie Stowell

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.
Brilliantly illustrated throughout by Davide Ortu, The Monster is the Lake is the funny, exciting, action-packed sequel to The Dragon in the Library.
