Children's book author Bonnie Bryant was born and raised in New York City. She became interested in horses as a child when she spent her summers in Massachusetts near a field of horses. She graduated from Lawrence University in Appleton, Wisconsin and returned to New York City to work for Scholastic, Inc. In 1983, she began writing books and her early works were written using her married name, B. B. Hiller. These books included Rent a Third Grader and novelizations of such movies as The Karate Kid, Teenage Mutant Ninja Turtles, Big, and Honey, I Shrunk the Kids. In 1986, she was approached by Bantam to write four books "about girls and horses," which eventually became The Saddle Club series written as Bonnie Bryant. She is also the author of the Pony Tails series and Pine Hollow series.
