I've just about finished reading Good Omens by Niel Gaiman / Terry Pratchett, but now I'm ready for something a bit different. I'm looking for something well written, with a lot of action / twists and turns, and..very importantly, interesting and enjoyable characters. Something along the lines of George R.R. Martins work/Game of Thrones. Anyone have a good recommendation? I want something that feels epic -- and is a real page turner -- if that makes sense. Thanks!
