I read all kinds of books (one of my friends jokes that I will read anything that holds still long enough), but sci fi/fantasy is my favorite. I also love books on anthropology and archaeology and other sciences.
This was absolutely adorable. It was fun to see the young boy grow up, and how the tree gave him everything because of how much the tree loved him. It is a great example of children's books because it is one everyone can get into, whether you're 9 or 90.
