Your Fav Fiction Genre?

That's a very cool way to put it.

And that being the case, Lore, what do you think are the best few hard-core sci-fi books ever? I ask because I'm looking for something a bit new to read. Fun though it was, I wasn't entirely impressed with Ender's Game, which was on several lists I saw.

Alastair Reynold's Revelation Space series.
Tau Zero, by Poul Anderson.
Anything by Dr. Gregory Benford (for example, Timescape).
Mission of Gravity, by Hal Clement.

I've only ever heard of Poul Anderson. He wrote one of my favorite books. Hrolf Kraki's Saga. Wiki says:

The novel is a retelling of the story of the legendary 6th century Danish king Hrolf Kraki, pulling together and reconciling narrative strands from such diverse traditional sources as the Danish historical chronicle Chronicon Lethrense, Saxo Grammaticus's Gesta Danorum, Icelandic sagas Hrólfs saga kraka, the Skjöldunga saga and the Ynglinga saga, Norse mythological poems Skáldskaparmál and Gróttasöngr, and Anglo-Saxon poems Beowulf and Widsith.

His Last Viking saga was fun, but historical-fiction, rather than fantasy. I definitely want to try Tau Zero. Thanks.
