"In the not-too-distant future, three astronauts land on what appears to be a planet just like Earth, with lush forests, a temperate climate, and breathable air. But while it appears to be a paradise, nothing is what it seems." (From the back cover of the Del Rey edition.)
Back in May when I read Pierre Boulle's Bridge Over The River Kwai, I learned he had also written Planet of the Apes
Don't let any cheesy old movies prejudice you. The book is surprisingly good! The writing itself does not come off as serious literature, but the themes sure do. Boulle considered Planet of the Apes to be a "social fantasy". It also could be a commentary on everything from animal rights, war, and racism to science and education. Seeing the apes engaging in so many everyday human activities and hearing their reasons for what they do brings to light irony and absurdity in our own behavior and prejudices in our logic. Believe it or not, this would be an excellent book club selection.
And for those who are wondering, the end is different from the movie. :-)
