The premise of this book is really unique and I appreciated the science lingo used by Sarah Gailey when writing this book. Even if you don't know a thing about science, the descriptions used in this book can be greatly appreciated. It really helped me get deep into the plot and characters. I guessed much of the major plot twists, but I found it still enjoyable to follow along. I am more of a plot gal, and this book focuses more on the characters and how they are feeling in the situation they put themselves in. I didn't enjoy that aspect as much. I wish there had been bigger plot details than what was given. Overall, a decent book with original thinking.
