This simple and timeless tale written by Shel Silverstein chronicles the lifelong relationship between a boy and a tree who loves him. She gives him shade, apples and a place to play, but, as the child grows, he demands more of the tree and she gives him everything she has. While this book is a "message book," it leaves much to interpretation, offering readers a chance to draw their own conclusions about giving, taking, and what it means to love someone unconditionally.
