On a scale of 1-10, I would certainly give "The One and Only Ivan" a 9.9. It is a great story of an animal’s life and tells what might happen when a gorilla gets shipped to the zoo. I recommend the book for ages 7 and up. It might be long, but it’s not complicated at all. The book also has some sad parts. I almost cried once. The characters are all very brave and willing to help each other. Overall, “The One and Only Ivan” is just a great and intriguing book!
