This might be The Book for me, the once-in-a-lifetime, everything-designed-just-for-you book. I loved the structure (HTGAWM-style literally flashing back to get you to murder night), I loved the adult detectives, I loved the doomed high school best friends - both groups. As a standalone, a pretty perfect novel. As the fifth in her series, I can't believe Tana French finally gave me what I'd wanted for two previous books WHILE ALSO hitting me right where my heart hurts the most so I couldn't even be happy. I hate that. I love that. I read the majority of this book on 1/1/17 and it was the best way to start the reading year.
