Listen to the Wind: The Story of Dr. Greg and Three Cups of Tea by Greg Mortensen is a lovely nonfiction picture book:
I haven't read the adult book from which this picture book came, but I'm familiar with the story. The collage-type pictures here are darling and the story itself is a tearjerker in a good way. For this reader and maybe others, it begs the question, "What can I do in my community?" And that's a good question to ask.
