Dystopia + romance = wow!

I've read dystopian novels (a lot) and romance (a little), and I was very impressed with that combination in Matched by Ally Condie.  Cassia lives in the Society, which determines everything about her life - what she'll eat, where she'll work, and when she'll die.  Now that she's turned 17, she'll learn who her Match is...the person she'll marry.  She's thrilled to find out she's been matched with Xander, a close friend from childhood.  But when she puts his microcard into her computer, she's stunned when an additional face is flashed before her - her friend Ky.  An Official later confirms that is was only a mistake, but Cassia starts seeing Ky in a different light.  She discovers romance and creativity, and soon she's questioning the idea of blindly following all the rules imposed by Society.  An excellent, thought-provoking story that's continued in the next book, Crossed.
