I read this in under 24 hours and was on the edge of my seat the whole time. There's at least one gaping plot hole, parts that are lacking explanation, and the entire thing is incredibly unrealistic. But this is the most fun I've had with a thriller in a very long time (maybe ever?). This makes me wonder if I've ever given a thriller a 5 star rating and I can't think of any. Such a hard genre to do perfectly.
