 This is a hard book for me to review, so I'll give a summary. Also, it isn't the sort of thing I normally read, and it sort of confirmed why. 
 Unlike a lot of reviewers, the book did not make my heart race or frighten me: it did make me feel sickened and sad, though the quick pace, sympathetic main characters, and twisting plot kept my interest until the end. 
 Pretty Girls is equal parts family drama, mystery, thriller, and slasher/horror, with surprising insight into the aftermath of tragedies and the way they can destroy a family. Seen through the eyes of the deceased father (through heartbreaking letters), and the two estranged daughters, Pretty Girls is fast paced and well written. That being said, it is yet another thriller that surrounds the abduction, rape, and torture of young girls, and gives us far too many details on exactly how that plays out. It's disturbing and disgusting, and a harrowing look at the most depraved side of humanity. 
 Due to the above, and profuse (though authentic) foul language and intense violence, I cannot recommend this book.
