70 out of 100 for 2010
Damon Knight was one of the true grand masters of science fiction; unlike many other writers, much of his writing is pessimistic and has a dark side, and yet it manifests iteself in a dark, quirkly sense of humor. This novel is subtitled "The Comic Novel of the Destruction of the Human Race." It's a good indicator of what the book is about.
Ed Stone was kidnapped in 1931 by aliens, and, the next thing he knows, he's back on Earth in 2002. He has been told that the Earth would be destroyed in about twelve years, and it is his duty to persuade the governments of the world to build a big box and to put everyone in the planet in the box. He succeeds, not because he's so persuasive, but partially because he freely admits that he might be crazy and is unsure if he is right. He has been given a special ring, though, so that anyone he actually has contact personal with believes him . . . for a while.
Predictably, forces also line up against him and denounce him as a fraud. And, although Ed is likable, you're not sure if you want him to succeed, or if he's a vilalin or not. And it'd a Damon Knight ending; I didn't really beleive the world was going to come to an end until it did. He also kills Ed off . . .but he is vindicated because aliens really do come and take the big box, which contains most of humanity, off the planet prior to its destruction.
If you like Knight, it's a great read. If you're not a big fan of old school SF, it might be an acquired taste.
