I've been reading more suspense lately and have been fortunate to discover some great authors. Peter Swanson is another one to add to the list. The idea of two characters plotting a murder didn't intrigue me as much as the idea that one of them felt absolutely no qualms about it--thought that some people deserved to die and that she was somehow noble in exterminating them from the earth. I had to see how this story would unfold. 
 It's hard to talk about the story without giving spoilers. There are unexpected twists and coincidences that force you to accept that we do indeed live in a small world. The very first coincidence occurs when Ted meets Lily in the airport bar, though as a reader you don't know it until much later in the novel. 
 I like how the author wrote each chapter in the different POV of the characters. I also liked the way Lily's background unfolded, so that as a reader I could better understand her and see how and why she committed murder before. And the ending...wow. All I can say is, she should have known better, because in the back of my mind I thought she'd made a dumb move when she hid that second body. And that's all I'm going to say about that. 
 Entertaining, suspenseful, and definitely worth the time spent reading it.
