I'm a slow reader, typically. Every once in a while a book will catch me and I can't put it down. Into Thin Air was like that, as was The Omnivore's Dillema. I read the entire Dune series in a few weeks one summer as well. The Hunger Games was like that. The first book introduces you to this less than ideal vision of the future. The story arc is easy but very fun and enjoyable. Recommended reading, particularly for a summer vacation.
My only critique of the book is the ending of the last one. I was left wanting more, something more interesting to happen. It wasn't that it was bad, I just wanted more story.
