About this series
A middle-grade series that began with Katherine Applegate's Newbery Medal-winning The One and Only Ivan, following the friendship of Ivan the gorilla, Bob the stray dog, and Ruby the elephant — inspired by the true story of a mall-circus gorilla. Concludes with The One and Only Family (2024).
