This was an interesting book about gorillas in the wild and in captivity. It mainly focused on gorillas in a family troop at the Lincoln Park Zoo in Chicago and the silverback Kwan. Many facts about gorilla behavior, the new ways they are kept at zoos, and their intelligence. I enjoyed the book quite a bit but must confess that by the end they were just so many different gorillas being discussed that it got a bit ho hum. For students really interesting in gorillas this would be a great read.
