Dystopian novels are popular in the YA genre -- and some of my favorites fall into this category. Delirium, which I read last year, was my favorite book of the year, and probably ranks pretty high in my list of all-time favorites, too. The Giver, of course, is a memorable classic of this genre. Others come to mind: The House of the Scorpion, for instance, and the more recent Hunger Games.
Matched falls into this category, and is in fact much like Delirium. There are some significant differences, though.
Like most dystopian novels, the world Cassia lives in restricts individuals' choices -- the government chooses your job, where you live, whom you marry. But unlike Delirium, where the focus was on eliminating emotions, especially love, and unlike The Hunger Games, where bloody gladiator-style battles were used to control the less fortunate, the dystopian society in Matched uses statistics and logic to make the optimal choices for everyone, even to predict what color of dress a 17-year-old girl might choose to wear to the biggest event of her life.
