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 by an angry mob, 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. All she wants is to return to her husband and children, still trapped under his baleful influence. Though they have nothing in common, these two unlikely companions must band together on a magical quest to defeat the evil that threatens Temperance’s family, Jenny’s lake and possibly the very soul of Britain.
