It's been said, but it bears repeating. Ally Condie owes Matched to Lois Lowry's The Giver. However, since that is my favorite book from childhood, I enjoyed Matched. In fact, I kind of found myself pretendingMatched was a sequel to The Giver, or at least in the same universe, and it made me happy, like revisiting an old friend.
Obviously, Matched doesn't have a lot of original thought. 17 year old girl lives in a future dystopia where the government controls everything from the food, to the clothes, to who you marry, to when you can have children. Something happens to open her eyes. Mild rebellion; mild rebellion; moderate rebellion; no rebellion, I'll be good; REBEL!
The love-triangle might as well have not existed. From the moment the dangerous choice was introduced, the safe option ceased to exist. One time, I'd love the heroine to realize that rebelling is too dangerous and choose the milquetoast childhood best friend. It wouldn't be interesting, but at least it would be a swerve.
