The first book in this trilogy is Matched. It is a well written story of romance. It is about this place where they control who you marry, what you eat, how much you get, when you`re allowed out of the house, and so muchmore. So this girl, goes to her match banquet, thats where they chose who you are going to be with. And she ends up with her best friend, Xander. While they are together, the end up seeing this other guy, wich she falls in love with, and she eventually finds out that they have an activity together (this place can also control wich school/summer activities to do) so theirs is hiking, and the guy and her are always first to the top of where they are supose to be. And as she learns more about him, she begins to lose feelings for Xander, and get more for this other guy. Yes, she ends up hurting Xander. And the other guy is being sent to this dangerous type thing, so he has to leave her, and she tries to find him, and Xander helps her, not because he wanted to, but to make her happy.
I would give this trilogy a 10/10 it is so sweet and so sad, and it makes the perfect romance story. It has a bunch of twists that you wouldn`t expect. The system they have in their world is so diffrent then ours. And everything that happens in just those 3 books, is super detailed, its really good. You should Definately read it!
