To fully enjoy this book you need to go into it blind. Compared to The Wife Between Us and its massive twist (you know the one I'm talking about), An Anonymous Girl slams you over and over again. It's not comprised of a single, twist; this one hits you time and again with OMG-Oh-No-She-Didn't whiplash. Every time you get used to or start to think you can predict whats coming next, *bam* theres a twist which totally changes the plot. It was the type of complex, thrilling novel of suspense that I have't come across in quite awhile. It's getting harder as an avid reader of mysteries to find ones that I can't figure out immediately, and this one proved to me that there ARE still new tricks and writing techniques that can be used to fool readers while keeping them engaged with the characters. And talk about some wicked nasty characters... My favorite!
