Katherine Applegate brings the tale of Ivan the gorilla and his pals to an affectionate finale, with lots of memories and lots of new challenges -- like the fact he's about to be a dad, and now what? As seen in Patricia Castelao's lively, sometimes poignant illustrations, Ivan, Kinyani, their twins, Bob the dog, Ruby the elephant, and the humans who love them are all part of The One and Only Family -- and it gives them all a strong foundation when things are at their saddest and scariest.

Did we miss something on diversity?

Research shows a connection between kids' healthy self-esteem and positive portrayals in media. That's why we've added a new "Diverse Representations" section to our reviews that will be rolling out on an ongoing basis. You can help us help kids by suggesting a diversity update.
