I recommend every single Discworld book. I haven't read them all, but of the 10 I have read I've not found one I couldn't specifically recommend.
And way too many books on my to-read list that I shouldn't come near this thread again. I've got Lord of the Rings trilo, Mistborn trilo, 6 more discworld books, the first two Game of Thrones, Neuromancer, Catch-22, Slaughterhouse-Five, Jonathan Strange & Mr. Norrel, and.... I'll just stop there and say there's a reason I forbid myself entering a Half Price Books. All unread just staring at me every moment I sit at this computer.
But trying to get through A Game of Thrones. I'll alternate it with a rereading of the first books of Wheel of Time.
