Cynthia Rylant, the acclaimed author of more than 50 books for young people, shines a gentle light on three talented writers: Margaret Wise Brown, L. Frank Baum, and E.B. "Andy" White (authors of Goodnight Moon, The Wizard of Oz and Charlotte's Web). Ryland details their struggles and successes, their fears and joys, and the special moments that helped shape their minds, their hearts, and ultimately their stories. Photos.
