Premise: A woman decides to get revenge after learning two of her students killed her daughter. I highly recommend going into the book without knowing much more than that. The first two chapters are so good and so intense. Perhaps I am a bit desensitized to disturbing stuff, but the middle of the book was a slog (rough for such a short book) as the same period of time was covered by several characters. However - it all worked out for a big finale, and it’s absolutely a disturbing and thought-provoking read. If you got the good creeps from the way The Troop included some not-so-innocent Scouts, I think you’d enjoy this.
