Beneath the still surface of a lake lurks a monster with needle sharp teeth. Hungry and ready to pounce.

Jenny Greenteeth has never spoken to a human before, but when a witch is thrown into her lake, something makes Jenny decide she’s worth saving. Temperance doesn’t know why her village has suddenly turned against her, only that it has something to do with the malevolent new pastor.

Though they have nothing in common, these two must band together on a magical quest to defeat the evil that threatens Jenny’s lake and Temperance’s family, as well as the very soul of Britain.
