While I've always admired Tana French's books, this one went on for way too long. I thought it was finished several times only to click on my e-reader to find yet another chapter. And yet... oh, does Ms. French understand the teenage female mind! She was so spot on about the way they think. Quite scary, actually - teenage girls can be quite vicious! And I did enjoy the interplay between the two investigating officers. So all in all, I enjoyed parts of it and thought the story was interesting but not one of my favorites that she's written so far.
