RIP David Gemmell, one of my favourites too. Although for me, I think The Knights of Dark Renown was my favourite of his books.
One of my overall favourites has to be The Gods Themselves by Isaac Asimov. Sci Fi at its best I think.
I've never read any of his other books as I thought there's no point. It's never going to be as good as the Troy books, but if you think it's worth it, I might give that book a go.
Call of the wild by Jack london is my own personal favourite. First read it when i was 12 or so. Must check out white fang.Two of my favourite books are White Fang by Jack London
The Hollow Chocolate Bunnies of the Apocalypse by Robert Rankin for me.
