A very solid four. Admittedly spent a bit of time thinking that I wasn't going to like Rachel--and then she went through a character growth spurt and all was right in the world. Also, this flowed so nicely that I had to--occasionally--go back and see whose PoV the chapter was in. O-o And I'm now left with two very large questions--courtesy of Defiance's ending--which I will not speak of. Let's just say that you'll probably be wondering about these things as well when you reach the end.
