Considered a classic in the SF genre and generally known as a must read.
A magnificent book, in my opinion. The first half of the book is very much SF, and very good SF at that. The second half spins off into philosophy while still in the context of the story. He really gives you some issues to think about. Some people won't like this, but I did. The ending took me a bit off guard, but probably shouldn't have. For all you avid SF readers who haven't read this yet, you should try to eventually get around to it. That goes for the rest of you, too.
