The One and Only Ivan by Katherine Applegate

 

It was about a gorilla who got captured when he was just a baby. He was brought to a mall to be displayed. There, he meets Ellie, who was also captured. Bella, the cleaner’s daughter, shares a special bond with Ivan through art. The plot thickens as a new baby elephant gets captured and used in a circus. But Ellie begs Ivan to save the elephant’s life because she doesn’t have much time left.
