I already did a topic on 1984, which encouraged some good discussion, I think. But that topic has died down a bit, and I'm pretty sure all has been said about that.
With current development, Watchmen would be a good choice. I've only started reading it yesterday (finished episode 3 today), and there's plenty of stuff to be discussed in there - the 'comic within a comic' (pirates or whatnot) that relates to the story of the novel, for example. And many more.
Other than that, I have this awesome book on computer organization, processor architecture, memory management, multi-threading, and the odd smart remark by the author (stuff like funeral cards with music and whatnot). It'd be awesome to discuss all that,
. But I doubt there's many people that would read that,
.
Other than that, I haven't read much recently. I started reading The Children of Hurin, which I could probably fill a few paragraphs about already (mainly in terms of the writing style up until now), but I dunno if that would be suitable.
