All Tally knows is that when she turns 16 she will have the operation that everyone has to make her a pretty. The life of a pretty seems glamorous and Tally is excited to be reunited with her best friend who had the operation before her. When Tally makes a new friend, Shay, she begins to question the life that she has always known. Her journey leads her to the Smoke where all the people who have escaped the pretty operation live. Tally fights an inner battle of turning her new friends in or staying in this free life she has found.
This isn't a book with a lot of action in it, so if that's what you are looking for, you probably won't find it here. If you are a fan of the dystopian genre, I think you will enjoy the first book in this series.
