If you like Girl on a Train- you will absolutely love this book. Absolutely incredible- perfectly written- read 150 pages in one night, could not put it down- has a bit of scariness to it- so be sure to have the night light on!
Interesting story, characters well written, while seldom likable. Keeps you guessing for a good amount of time - you don't see the end coming.
I will probably read this author again - at least her books are reasonably priced and, more importantly, don't take a hard left turn after the sample finishes like a lot of previously famous authors' books do now.
This was a very enjoyable book. It kept me guessing and turning pages from the start. Highly recommend it and look forward to Katherine's next book.
