Manna is the closest I can come to identifying what guile may be. A young orphan, Yonnie Watereye makes her living by conning people into believing she can sense and identify guile while it is really LaRue. I guess my best description of the book is that it is a coming of age story with supernatural overtones.
I always have a fondness for cats, let alone ones that talk. That provides an interesting turn to the story. The book is a bit strange but so is the protagonist.
I enjoyed it.
This book may have been received free of charge from a publisher or a publicist. That will NEVER have a bearing on my recommendations.
