Miss Little's Gift

Miss Little's Gift by Douglas Wood, illustrated by Jim Burke, Candlewick Press, 2009, ISBN 978-0-7636-1686-1
Tells the author's own study of battling ADHA as a child, and of the patient teacher who helped him learn to read. It's all about "the importance of the right book at the right time, and ...the impact of a good teacher." (book jacket)
By the way, the "right book at the right time" for Douglas was The Little Island by Golden MacDonald (a pseudonym for Margaret Wise Brown), which was first published in 1946. It won the Caldecott Medal for Leonard Weisgard's illustrations.
