Butterfly Tree, written by Sandra Markle with illustrations by Leslie Wu, revolves around a little girl who comes upon a wispy orange color in the sky and summons her mother to help discover what it is. They walk swiftly down the beach and head into the woods. There they see thousands of monarch butterflies in a tree. On the way back, they walk slowly as her mother tells a story from her past and together they harvest a new memory they can cherish together for the rest of their lives.
