Greenteeth

"Beneath the still surface of a lake lurks a monster with needle sharp teeth. Her name is Jenny Greenteeth, and she is hungry and ready to pounce. . . . She 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 instead of eating. Soon she learns that the witch's once-peaceful village has suddenly turned against her-- and that it has something to do with the malevolent new pastor and his wicked influence on the townfolk. Though they have nothing in common, Jenny and her unlikely companion must band together on a quest to defeat an unforeseen evil that threatens the very soul of Britain."--
