This was not one of my favorite installments in the series so far. I thought that the whole controlling people's emotions ssemed almost too easy an out. There really wasn't much that Eve could investigate and anything she did figure out (like the "murderer" at the end) was almost just happenstance. Meaning, if she wasn't in the place that she was at the time she was, she wouldn't have figured it out. I know she was making progress and it probably would have eventually led to a connection, but we didn't get to see it go that far, so it felt really incomplete to me. 
 But with that said, I think if JD Robb maybe could have committed more to it, it could have turned out a little better. It's definitely a subject that makes one this about subliminal mind control. It really seems plausible. 
 Again, I like the Roarke and Eve relationship. I don't feel like their becoming too settled which can be an an issue when characters are in a relationship so early on in a book series. We get to see a little of a darker Roarke when dealing with the mind control. I like that we get glimpses of both of their pasts without having everything just flat out explained to us. 
 I hope this isn't a bad omen that the books will start to down in quality. I;ve really liked the series so far and I would hate for it to become too predictable or unbelievable. I am planning to continue with the series, I like that it's the kind of series you don't really want to read back-to-back that way when you do come back to it, the stories don't seem so repetative. Robb has been following the same progressive outline for the series. If you don't read one right after the other it doesn't seem as similar.
