Thanks for the recommendation Hophead, I do like sci-fi. I have read one of Arthur C Clarke's books, that being Songs Of Distant Earth, which I enjoyed, the main reason I read it, which was back in 1997 was that being a Mike Oldfield fan, I was intrigued, because Mike had written an album based on Mr Clarke's book of the same name. The album of course is amazing. And at the end of the book there is a concert, which gave Mike the idea to make an album

I have heard that Rendezvous With Rama is a classic, so I'll check it out
