Have you ever read a children's book by Mark Twain? No one has—until now. Handwritten notes found in the Mark Twain archive sketch out a bedtime story he told his young daughters. Caldecott Medal winners Philip and Erin Stead fleshed out Twain's notes into a complete story with enchanting illustrations. The New York Times calls this book "a rediscovered Mark Twain fairy tale," which is a very big deal. Hardcover, 160 pages.
