Terry Pratchett books don't really have any epic battles as such, but some of them are really good for a laugh. They are very Brit-specific in their humour, but they also create a very interesting fantasy world. There is an online store where novels set in the world of fantasy games I have played can be bought here. I don't know if that will help much. I've only read a couple of the Gotrek & Felix books, which were good once I got past the writer's tendency to write paragraphs a mile long. Stephen King also has a novel called The Eyes Of The Dragon which is supposedly a good fantasy tale.
