Every day, the train stops or slows at the same signal - right behind the house where Rachel lived with her now-ex-husband. Her life's not so great, and it's a small pleasure to make up domestic stories in her head about one set of neighbors who she glimpses almost every day. Then one day she sees the woman kissing another man. The next day, the headlines indicate that same woman is now missing without a trace.
Critics love to say a book is hard to put down, but that really is the case sometimes; this story hooked me early with a narrative peek into the private lives of these women. Chapters alternate between Rachel, her ex's new wife Anna, and the missing woman (from a year prior). I consumed the book over a weekend, and will be recommending it to fans of domestic suspense.
