My first thought too. fantasy is not science-fiction, and science-fiction is (pretty much) not fantasy. Admittedly, there are some authors like Ray Bradbury who have a foot in both camps, but my preference is (generally) for science-fiction over fantasy. Probably my favourite book is Arthur Clark's 'Rendezvous with Rama', though I felt the later 'Rama' books weren't anywhere near as good as the first in the series.
