You're looking for pure fantasy I can't help you but fantasy / sci-fi -- I like the Culture series of novels by Ian Banks. For fantasy / comedy, nothing beats Terry Pratchett.

Gene Wolfe writes sci fi and fantasy but even his sci fi is fantasy flavored. Jim Butcher is great too. I read both Sci Fi and fantasy with a bent towards Sci Fi. The Shannara books by Terrry Brooks are great too. Bernhard Hennen has written some books about Elves that I would recommend. Jeff Wheeler's books are top notch too. Kevin Hearne's Iron Druid books are great too.

I read true crime and reality about bad things ie gangsters, the holocaust etc and I'm running out of things to read on the loo. I can watch fiction but hate reading it.

Terry Pratchett is an obvious suggestion if you enjoy fantasy. Some of his books, if we're being honest, are not so good; others are very good indeed. They're all readable though, and there's plenty of them and they're widely available - so he'll keep you going for a while.

For slightly heavier sci-fi based fantasy/space opera, you can't go wrong with Iain M. Banks. Excession is a good place to start.

Fantasy? Go to the roots. Robert E. Howard, Michael Moorcock, Robert Zelazny, Tolkien (of course). Then there's intermediate stuff like Piers Anthony, Poul Anderson, Fritz Lieber...
How about collaborative efforts like the Thieve's Guild series? Wonder if anybody does that anymore.

You may enjoy he books by Kate Wilhelm. She is categorized as a Science Fiction writer, but you will find her scope much broader and her style fascinating. And if you like whimsy with a dark edge, try Terry Pratchett.

When I was very small , my Mother would read to us from a book , she had been given as a child , which included Greek and Roman myths , which is , I believe, what your book was about . I tend to go through phases . From fantasies , I moved to SciFi - lots of good authors there . For a time I was interested in the Barbarian stuff (Conan), I moved on to SIr Author Conan Doyle ( Sherlock ) , Agatha Christie (Murder Mysteries ), Mary Shelly (Frankenstein) . The English books ( Pride and Prejudice and Sense and Sensibility ) .
