I've always liked Lauren Oliver's books, and Vanishing Girls was not an exception. However, this is definitely not one of my favorite books. 
 The book is a young adult novel, with teenage sisters being the main characters. However, adults who enjoy emotional, kind of dark, but realistic books would like this too. I will admit to crying about halfway through the book, during some particularly emotional parts. 
 I like the writing style, and I love how Oliver included news excerpts between chapters. I always enjoy it when books do that. However, there were a few excerpts that I found pointless. I also didn't like the constant reminiscing. I mean sure, for a book that focuses mainly on the characters, the flashbacks are super important, but I didn't like how every other paragraph was about "when we were little..." After reading the ending, I realized these flashbacks were necessary to truly convey the emotions, but I'm still not totally crazy about them. 
 Overall, Vanishing Girls was a pretty good book.
