I don’t know why I waited. It’s a quick read and a very cool book.
It’s set in New York City in the late 1970s. Miranda, a sixth grader, lives with her mother. One day she finds a mysterious note stuck in her library book. It asks her to write a letter and to mention the location of her hidden house key: It says: “I am coming to save your friend’s life, and my own… The trip is a difficult one. I will not be myself when I reach you.”
