I know there was a thread like this, but I couldn't dig it out of the pile...
I'm about 200 pages into Neil Stephenson's new novel REAMDE and it is awesome.
The main character is based loosely on Richard Garriott (Lord British of Ultima) and the background is hsi company which has basically married Bitcoin to an MMO and created this ridiculous gold farmers dream of a game. Enter a new virus that basically encrypts your HD and holds it for ransom unless you pay 1000g of in game currency (about $73.00 real world) and the russian mafia and you get a really cool novel.
I am a big fan of his (Snowcrash, Diamond Age, Cryptonomicrom, Baroque Cycle Trilogy, Anathem) and his books are all on my favorite lists.
