Amy Hest is a quiet giant of picture book writing whose name you may not know. The noisy giants, those with name recognition, tend to be author-illustrators: Sendak, Seuss, Steig, Carle, and more recently Blackall, Lin, Klassen, Morales. Less likely to be on your radar are authors who don’t illustrate, people whose books look different from one another because they’re illustrated by different artists. Over the course of 38 picture books, plus many chapter books and middle grade novels, Hest has paid the utmost attention to the emotional lives of her young characters.
