I really enjoy reading this book. Because it has unique phrases to describes a character. Ivan is the main character of this book. He have a deep thoughts and feelings. Being a silverback gorilla who stuck in a cage is not easy thing to do for him. I love the different point of view how we see gorilla and how they see the world and humans. Humans can be advantageous or disadvantageous to the animals. Because Ivan and baby elephant Ruby has a different memories about humans. Ivan lost his family because of humans violence but for Ruby human helped to save from the danger.
