Arthur C. Clarke was always keen on incorporating the latest scientific discoveries into his works, and when a flyby of the most famous comet of them all - Halley's Comet - by the probe Giotto revealed an icy surface ravaged by guysers of gas and liquids as the sun boiled away the water and hydrocarbons, Clarke saw a scenario that could get Dr Heywood Floyd out of retirement.

With the return of Halley's Comet in 2061, a luxury trip is proposed which Floyd's sense of adventure can't resist. However when things don't quite go to plan his resourcefulness comes to the fore - as well as his connection to long-lost astronaut Dave Bowman and computer HAL9000.

As a neat piece of science fiction, leaning heavily on the science, this books works well and it's a compelling read, especially the encounter with the comet, a world so utterly alien Clarke does well to capture it in his descriptions. As a sequal to 2001 and 2010 it works perhaps a little less well as it doesn't have a great deal to do with the future of mankind, as the first books do. The sequence around the comet would have worked with any protagonist, it didn't need to be Floyd, but would have been a shorter work. But it just about fits into the Space Odyssey ouvre and it's always good to meet up with old friends.
