He passed away about 2 years ago mate. He had only written about 70 000 words for the last book in the Troy Trilogy as well. His wife Stella finished it, with Davids guidance before he died. I found myself trying to pick out lines and paragraphs that may have been written by her and not David but shes done such a great job. If you have read the other 2 then you have to finish it. I know its stupid as everyone knows the story of Troy, but I still found myself hoping the City wouldn't fall, that somehow Agememmnon would fail. And I agree, he was the best ever fantasy writer, no question in my mind. I could read his books over and over again and never get bored of them.
I've read a fair few of his books, but i've made a point to not buy all of them at once, so i can enjoy them more. Have a good few to read yet. Have you read any Raimond E. Feist by any chance?
