Michael Elsohn Ross is the author of more than forty books for children, most about science or world cultures. He lives right next to California's Yosemite National Park, where, for close to thirty years, he has been working as a naturalist, taking visitors on hikes and walks to learn all about the park. His ideas, he says, "come from my work as a naturalist and my adventures with school kids."

Paul Meisel is well known for his illustrations in more than thirty children's books, including the Cool Crazy Crickets books by David Elliott, ALMOST LATE TO SCHOOL and other picture books by Carol Diggory Shields, and books in the Let's-Read-and-Find-Out science series.
