Cassia has been Matched with Xander, her best friend. Virtually unheard of, Cassia is pleased she doesn't have to wonder what her match is like. When she puts her microcard of Xander in her screen at home, though, someone else's face pops up for a few seconds--Ky.
Cassia's told Ky can't be Matched with anyone, but she can't help but wonder. The two of them are thrown together, for hiking, leisure time, and in her neighborhood. He's from the Outer Provinces and while at first that scares her, she becomes fascinated. Her feelings begin to grow, especially when her Grandfather gives her an illegal poem, Ky teaches her how to write, and she begins to question the Society, Officials, and her life.
Then Ky is taken away. Cassia has to decide where her loyalties will lie.
This is the first in a series. I liked how the book unfolded, and Cassia's growth. A lot happens in the book and most of it seems important in one way or another. In a way it reminded me of The Matrix (everything reminds me of a movie!)
