Query: A Worthwhile Mirror!

Sadly, this imaginative book has been overshadowed by the movies and TV series. Overall, this is a solidly written sci-fi novel. It starts with a couple finding Mr. Merou's manuscript in a bottle. Fine, a cliched begining. But, the pace soon picks up. In 2500 professor Antelle and doctor Levain set off on a spaceship journey. They reach their destination to an earthlike planet. They run into mute humans and than the sky figuratively falls. They are captured by talking Apes-military class, who rule the planet with Chimpanzees-middle class, Orangutans-ruling class who live as 20th century humans. This reverse world is riveting for it holds a mirror to the reader of how awful humans can be. Merou wins some simians over, but he is a threat to the established order. Finally, Merou flees and returns to earth, where he gets a jolting surprise. Despite, some oversimplifications the action and premise are very compelling.
