I managed to get through Dune somehow, in High School, but didn't much care for it. Haven't been tempted to read any others ever since.
I've just finished re-reading The Hydrogen Sonata. The better Culture novels are very fun indeed. The rest are a mixed bag. But I'd have to count Banks as one of my favorite sf writers of the last 30 years or so.
I'd be interested in reading some of the Culture novels.
Which ones would you suggest and what order should they be read in ?
I would suggest "The Player of Games" and "Look To Windward" in that order. But I very much suggest first reading an essay by Banks titled "A Few Notes on the Culture" before any of the novels. It will give you the lay of the land. It's in the story collection "The State of the Art." Then you might read the title story in that collection, "The State of the Art," a novella about a Culture Contact ship visiting Earth in 1977. I read the story first and THEN the essay and wished I'd done it the other way 'round. I remember finding some terms a little obscure (such as 'Orbital' as a name for a type of habitat) but then the essay made them clear.
If you read the essay and don't like it, then you need go no further. Then if you don't like the novella, you need go no further. I went on to read everything, but I really wish I'd read "A Few Note on the Culture" FIRST, although reading it second certainly didn't kill things for me.
