Ty lives in an underwater colony that was formed after the earth started to fall apart. He meets a Gemma, a topsider searching for her brother and decided to help her. Ty is also dealing with his life and trying to be normal struggling against problems with the government and dealing with his own self.
I typed out this whole review and lost now I am retyping and I just know this one wont be as good, so I apologize in advance. Ty is an incredible character and was extremely likable and easy to relate too. His sister Zoe is also a great character and I kind of wish we saw more of her in the book. The way people live in the colony makes people grow up very quickly so Ty is extremely mature but like most teenagers still a little bit lost when it comes to figuring himself out, although his situation is probably a little bit stranger then most.
We don't get a lot of information about what living up above is like. Just little scraps here and there and most of it is extremely negative. However the descriptions of sea life, both animal and how the people in the colony live are just incredible. They sound amazing and gorgeous, and just incredibly smart.
Although this is not exactly the kind of dystopia we are used to seeing, mainly because the people from the colony live so separate from the colony that the day to day life seems quite normal. It is only the large deprivations that the government infringes on the colony that are seen. This definitely could has strong themes and ideas of how much power a government should have both over it's people and it's colonies.
