If you haven't read yet any novels written by Sara Shepard one aspect that should convince you to pick up one of her books is the fact that they are simply unputdownable, addictive, vivid and very entertaining. Do you know that feeling when you thoroughly enjoy a TV series and instead of sleeping you keep watching it all night long like a madman? This the kind of experience that I have every time when reading one of her literary works. There is no doubt that the stories she writes are bound to become a commercial success because they are very modern both in terms of the writing style and the themes, the characters, etc. In most of her novels, including The Perfectionists duology the focus is on the teenagers' lives and Sara Shepard is an expert when it comes to giving details about their personalities, their physical appearances, their families (which at first sight appear to be perfect but in reality they face many problems), their friends, their day-to-day struggles, their love interests. As a teenager is relatively easy to emphatize to a certain degree with the characters Sara Shepard creates and probably this is one of the reasons why her novels become bestsellers. Yet, one bothering thing about all her series is the fact that most characters are super rich, live in enormous mansions, go to expensive high schools, attend fancy parties and this is somehow rather superficial from my point of view. 
 Regarding The Good Girls, the second and final installment in the The Perfectionists series, it is the 8th novel written by Sara Shepard that I've read so far and once again I found myself completely captivated and filled with curiosity to find out who was the real criminal. The first novel, The Perfectionists, was merely an introduction because it presented the main characters, five adolescents, and the situations they found themselves in: Ava, Mackenzie, Caitlin, Julie and Parker. Except the friendship between Julie and Parker, the other girls barely knew each other, the only thing they had in common being the fact that they were students of the same high school. Actually, they had something else in common as well: EACH ONE HATED ONE PERSON for different reasons but I'll let you discover the identity of these persons and the reasons why the girls were hating them. It is obvious that in what concerns the plot construction Sara Shepard inspired from Agatha's Christie famous novel And Then There Were None. At school, the girls form a group in order to discuss about the movie based on Agatha's Christie novel and they soon discover that they all hated one person from school, Nolan Hotchkiss and they plan together to prank him at an upcoming party. However, their prank turns into a crime and now the evidence indicates that they could be the criminals. 
 In my opinion, the second novel was better, because it gave a mind-blowing explanation regarding the identity of the criminal and his or her motives behind all those crimes that he or she committed. In the middle of the book there is one important revelation and at first I thought that it was the final twist and I felt somehow disappointed, expecting more from Sara Shepard. Because I was silly I quickly jumped to conclusions, although in the end it turned out that I was wrong: THERE WAS ONE MORE TWIST I DIDN'T EXPECT . 
 If you're looking for profoundness and a meaningul and powerful language this series is definitely not for you. But if you're interested in reading a suspenseful, full of twists series, which I like to call "guilty pleasure", that keeps you wide awake, then you must read The Perfectionists. It is truly great!
