What are the motifs in Matched by Ally Condie?

Just as love is a main theme in this novel, so is self-sacrifice. In the world run by rules, individuals show love and compassion for each other by breaking the rules. If they are caught, they are labeled by Society. Ky was labeled because of his father's actions, yet the label meant that he had a horrible job and couldn't participate in "normal" Society activities such as receiving a Match.
