I have mixed feelings about this book, and I kept going back and forth during the generous three chapter sample - it's set in a future world in which the humans have ruined the earth so there are only three communities to live in, and only clones inhabit it, until a human boy is thrown in the mix. Now I feel like I've read plenty of "humans ruined the earth now we only live within these walls but a small group of us want to revolt and see what is outside." However, the way the clones treat the human is so parallel to how our divided country is treating some people. I didn't think I'd be able to tell the clones apart at first, since each group has the same name and a number after it, but it's been pretty clear. I'm definitely intrigued and would like to learn more.
