J. Patrick Lewis is the current Children’s Poet Laureate. A twin himself, he has written more than seventy children’s books, including Once Upon a Tomb: Gravely Humorous Verses. “Being a twin is the third best thing that has ever happened to me,” he says, “after having wonderful children and grandchildren of my own and eating my mom’s apple dumplings.” J. Patrick Lewis lives in Ohio.

Jane Yolen, not a twin herself—but with multiple sets in her family—is the recipient of the Sydney Taylor Body-of-Work Award in recognition of the more than 400 books she has written for children and young adults, including the Caldecott Medal winner Owl Moon and the New York Times bestseller How Do Dinosaurs Say Good Night? With Candlewick Press, she is the editor of three collections of poems for children: Switching on the Moon: A Very First Book of Bedtime Poems; Here’s a Little Poem: A Very First Book of Poetry; and This Little Piggy: Lap Songs, Finger Plays, Clapping Games, and Pantomime Rhymes. She divides her time between Massachusetts and Scotland.

Sophie Blackall is the acclaimed illustrator of more than forty-five books for young readers and a two-time Caldecott Medalist. Born and raised in Australia, she now lives in Brooklyn.
