It's nice to re-discover how good a good book really is. I knew Game of Thrones was really good (they're making a television serious out if after all), but I'd forgotten how good.
When I was a kid I liked to re-read Fantastic Mr Fox. Since then I haven't re-read many books but David Eddings series with Spahawk as the main character (I can't remember whether it was the Emerald Throne or something like that... ) anyway, nothing better than re-reading a fantastic book to find out it is even better than you remembered!
It's already started. It's on HBO, though, so you don't get it unless you pay the extra money. Which I don't, so I'm waiting for it to become available on Netflix.
