This book predates the Hunger Games trilogy by almost 30 years, but if you liked HG, I highly recommend this one. I can't believe I missed reading it in my own teen years, when it was freshly printed. Glad to have caught it now, though, and I'll be picking up the sequels in short order.
Note: Apparently it's been optioned for a film, hopefully HG will be a success and this will get made. Moviemakers running out of cartoon characters for inspiration would do well to look to a lot of the older SF classics, now that technology has made the special effects and settings needed possible.
