This book was so amazing. It has such a chilling and interesting concept that makes you reevaluate your opinion about authority and gender roles as well as the meaning of "perfection" and "beauty." I love this author and can't wait to see what else she is working on. I 100% recommend you read this. It has a combination of romance, thrill, defiance of authority, and friendship that melts your heart and keeps you craving every page. I read the first 248 hundred pages in school the day I checked it out... I couldn't put it down.
