I've been reading about and seeing this book everywhere - magazines (EW, trade publications), Facebook, etc. It looks very compelling, the next, new exciting, "everyone will be reading" thriller. It reads fairly well. It grabs your interest pretty quickly. I'm sure it will be optioned for a movie very soon, if it hasn't already. It seems like it has a lot of twists and turns. It will challenge any assumptions that you make about the characters or action. I'm sure that there will be some sort of surprise/twist ending, like Girl on a Train and other thrillers of that ilk. I wanted to read this before I had sampled it. And now, having read the sample I will definitely seek this out to read and hopefully, recommend.
