I am blessed in that I don't remember a lot about this book anymore so I'll certainly be less vitriolic than I was right after I read it. I thought the premise was interesting, obviously, and the pace was fast so nothing ever dragged, but I could not care less about anything that happened in this book.  The characters were flat and their relationships were superficial, I didn't feel the our protagonist cared at all about the death of her daughter, and the ending was absurd.

There was one twist early on in the book that I thought was compelling, so I'll give it that much, but even then it didn't seem to have much consequence for the rest of the plot.

Don't waste your time here; at least the book was short so I didn't spend too long on it.
