This book by Meredith Ann Pierce has been one of my favorites for quite some time. I always finish it thinking that the ending was a little weak-- and weird-- but I like the beginning and middle so much that I always re-read it. Treasure at the Heart of the Tanglewood is about a girl named Hannah, who lives in the middle of the Tanglewood in a hut with her companions: Badger, Magpie, and three mischieveous fox pups. They can talk to her and she can understand them, unlike the local villagers, who keep their distance unless they need medicinal assistance (for Hannah is a healer). She is also the ward of a Wizard, and each month she must brew a special tea for him. Thus she has always done, for as long as she can remember.
Before long, Hannah starts to realize how odd it is that neither she nor Magpie nor Badger (not to mention the too-young fox pups) can remember how they came to be living in the Tanglewood. What is love? Who is the Wizard, really? And why do young, handsome knights keep venturing into the wood? As Hannah begins to discover the answers to these questions, she also eventually discovers who she truly is and the power that lies within her.
