I just finished Matched by Ally Condie . It was excellent, I highly recommend it. It is a(nother) YA dystopia. What I found interesting was how the author manipulated the limited point of view of the main character to have us, the readers, brought along on the journey to see how the existing Society was oppressing the main character and all of those she holds dear. The fundamental conflict is a love story conflict, but the book was recommended to me by a friend's 16 year old son, so I believe there's plenty in it that would appeal to males and females.
Matched opens with the main character getting ready for her Match banquet, where she'll learn who her Match will be with all the other 17 year olds from her borough. Unlike the other kids, though, her Match is someone she already knows, a boy she grew up with who is already dear to her. Later she looks at her microcard with her match's info, which she doesn't need since she already knows him, and for a brief moment a different boy's face pops up as her Match. Problem is, she ALSO knows him.
So the main conflict begins with Cassia's curiosity about the other boy, Ky, growing, all while she's starting to notice the oppressive aspects of her Society, such as the three pills they're all required to carry at all times (red "for emergencies", blue that can provide nutrition for three days, and green to calm down) or the fact that at 80, you die. Everyone does.
Because of the love story premise, I'd keep this in the upper middle school/high school age range for recommendations, but there is no overt violence or sexual content so it could be appropriate for younger readers (just might not be that interesting.) The parallels to war time oppression and oppressive regimes in modern day are very interesting and could lead to great book group discussions.
The pace is quick and I found myself enjoying the way the author unveiled the story so much that I slowed down in reading it, which is something I do sometimes when I want a book to last. I felt the characters were very believable, and even though it's a love story, really it's a rebellion story, and that made it very very interesting.
