I liked this, it kept me pretty captivated - afterward reflecting on it I question some things, but overall it was a good thriller. It's received some mentions from friends/Facebook. Glancing over the other reviews, I didn't see any immediate comparisons to [book:Room|31685789] which surprised me, as they do have some strong similarities. A little bit to [book:The Butterfly Garden|29981261] too, although the latter is a little "more". 

The chapter set up here was unique and probably what will be the most memorable to me.  The blurb states this story is told from the perspectives of three women "His 13-year-old daughter, his girlfriend—and the one victim he has spared" although "spared" is a misnomer ... he just hasn't killed her, yet. She/"Rachel" is the most prominent storyteller, she gets the most chapters. Unlike Cecilia and Emily (daughter and latest love interest) whose chapter headings are their name, our captive is "The Woman in the Shed" ... and that status shifts throughout the book (becoming "The Woman in the House, The Woman-Before the House, Before the Shed and more). These headings were interesting and illuminating. These portions were also ... would you call it "second person"? It's saying "YOU" but while that does help to pull the reader in and make them imagine they were in that position, it's not indicating the reader really. It seems more of a disassociative thing. It does really set these portions apart. They are in present tense, even when shifting to the past. Emily/Cecilia are told in the traditional 1st person, also present tense. 

There are some portions in past tense - not indicated in the blurb, but in addition to "Rachel" and Emily and Cecilia ... we also get the POV of the other victims. These are past tense. The headers for these chapters are Chapter Six: Number One, Chapter 12: Number Two, Chapter 22: Number Three, etc.  This felt a little like [book:The Shining Girls|16131077], which had a similar "victim perspective" right before they were killed, as did the start of [book:Follow the River|138872] (completely different genre/historical fiction, and only at the start during the Indian attack). 

This, and Room/ButterflyGarden ... the "bad guy" is keeping a woman to have her there for sex whenever he wants. And it seems to be daily. You hear that rape is more about power/control than sex, but is that the case here? Is it sex they want, however unwillingly given? Is the power/control?

We never really got to learn about Aiden, about his "why" or who he really was.

Not suitable for every bookclub, but there could be quite a bit of discussion here.

There was quite a bit of proFanity (50x) and while the sex was never graphic, in fact, barely mentioned (the sound of a zipper, and after he got up ... ) - it IS still rape even though she isn't fighting him.
