There's a lot that happened in the book, and I thought a lot of the loose ends were tied up really well. I enjoyed it a lot, and things were definitely changing for the girls and in Rosewood. It was pretty hard to put down, because I wanted to know what was going on. In fact, I think it might be my favorite out of the four. As for A, I didn't see it coming AT ALL, and yet it wasn't a surprise to me. It could have been a number of people, but Mona as A made a lot of sense. 
 Rating: 4 out of 5. It did seem a little rushed, but apparently it was supposed to be the last one in the series.
