The set up for this book was very good. The idea was excellent. It was similar to a lot of dystopian novels with hints of science fiction and romance which made for a very interesting mix. The setting was on a different planet, Kiel. The main character, Clementine, is from the surface. Everyone from the surface goes to school and until they are 16. When they turn 16 they take a test to find out what their "promise score" is. If they are in the top ten then they are "extracted" and get to live in the core. If they are not selected they are either replaced or they are simply killed once they turn 20. Everyone alive on the 20thbirthday dies. The moon spews acid which can kill someone in 10 minutes. The core set up a force field to protect against the acid but sometimes it leaks. As always in books, the main character is selected to live in the core. Her only problem is that leaving the surface means leaving Logan, a 17 year old. When she leaves Logan she plans to get an audience with the leader of the planet, Commander Charlie, and convince him to bring Logan to the core. There are other sections of the earth, the mantel and lower among them. Extractions come from those sectors as well and they are trained together. It was a very interesting idea and was executed fairly well.
I didn't think all of the characters were explained well enough. I think that all of the characters had potential to be very interesting but in the end, some lacked complexity. I don't think this is true for all the characters but I think it is especially true Sam, Ariadne, and Logan. Sam was a bully in the Core who had a high ranking. Ariadne was another girl from the surface who was roommates with Clementine in the core. Logan wasn't in the book that much so it is understandable but I think a greater connection between Logan and Clementine could have been established before Clementine is selected. Being in the moment when they are together would have been more powerful than just the thoughts that Clementine has in the Core. Ariadne definitely wasn't explored enough. She was kind to Clementine but was easily overcome in the core and could have been a very interesting character if she had had a bigger role. After a certain point in the book we never hear about Ariadne again. I think Sam was the most one dimensional character. He didn't seem to have any emotion other than anger and lust. I don't quite understand his fixation with Clementine. Sam was very competitive and Clementine threatened his authority so it made sense that Sam hated her but it was odd how much he hated her and how much he pursued her even when she wasn't doing anything.
Overall this book was pretty good. I was just like, well, a clementine. Juicy and sweet. Although, sometimes peeling the clementine can be a little frustrating. Overall this book was a 3.
