Greenteeth

 Greenteeth by Molly O'Neill, 304 pages.

Jenny Greenteeth has lived in her lake for longer than she has bothered to keep track of, and very little has changed that's seemed worth her notice. Then a witch in irons is thrown into her lake, and Jenny takes an interest despite herself, saving the witch and quickly becoming embroiled in a fight against the evil consuming the heart of the town. Jenny isn't the type to go galivanting off on adventures, but it's her lake, so she will set off with the witch Temperance and a frenemy of a goblin peddler to find a way to fight the evil threatening her way of life.  

This was a really fun fantasy novel! It draws on a lot of more obscure English and Welsh folklore to create a fairy story that feels very fresh and different. Jenny herself is also delightful, with an unapologetic monstrousness tempered by a surprisingly tender streak. The blurb for this book describes it as perfect for fans of T. Kingfisher, and that is definitely true.
