picked up Hunger Games for a few quid (haven't seen the film) and i'm thoroughly enjoying it. Think I might just have to read the trilogy but after that I'll be picking reccomendations from this thread so keep them coming! I couldn't really read back home because my family house is crazy noisy with dogs and kids and shit but it's really peaceful out here and it feels great to be reading again...a forgotten treat.
Unfortunately I would not recommend reading past book one. The subsequent books oversimplify the themes from the first book (apathy to violence, viewing other societies through your own cultural lens, effects of war on children, etc) into basically "capitol is evil", and make the story more about katniss herself. The second book was easy to read because there was a lot of action, but the third one is basically a teen drama with one-dimensional characters. Neither really has the emotional effect that the first one did, though that might be because the concepts weren't new to me anymore.
If you're looking for a solid sci-fi book check out
Snow Crash by Neal Stephenson. It's an action/mystery book that is one of the most exciting things I have ever read, and it's very highly reviewed (on time magazine's best books iirc).
When I was much younger I read
Ender's Game and that was my favorite book for a while, and when I re-read it a couple years ago it was still fantastic. It's a pretty quick read too, though at times you have to keep in mind that it was written for a younger audience (no different from the hunger games i suppose).
If you're more into books with aliens that save humanity and then interbreed with it, then the
Lilith's Brood trilogy is for you! Although a lot of crazy shit is going on with humanity, the books are really about the development of the narrating character (Lilith in the first book, and one of her children for each of the next two). It's a very personal book, pretty much devoid of action but has the whole "psychological thriller" thing going on to keep it interesting.
Lots of apparent sci-fi fans in this thread, thought I'd give you all some good reading!
