He was my favourite author. I think I've read pretty much everything he wrote, and in the case of some of his novels I've re-read them several times.
Rendezvous with Rama will always remain my all time favourite book. I've lost count of how many times I've read it, and I'll probably read it again this week. I'm really hoping they make the film that has been mentioned and make a good job of it. If Zodiac is anything to go by David Fincher may well be the perfect director for the project.
