I was immediately engaged in this world where the cunning folk are turning into trees... and my heart was with Grayling as she set out (reluctantly) to save her mother. There's also a shape-shifting mouse (among other witches, enchantresses, etc) which adds a certain charm to the story.
My favorite quote:
"Like simmering soup, stories cannot be hurried."
Isn't that a great reminder to those of us who tend to rush along?
Read this book. It's a magical experience.
