I have mixed feelings about this one.
The case was too intricated, sometimes it was hard to comprehend and follow up. But, at the end, it's satisfying when all the pieces fall into place. Besides that, the case that was fully detailed, I guess that what I'm feeling from this book is the absent of depthness in another matters.
I know it's a crime novel, but it is also the seventh book of Nikki Heat, so I think it should have had more relationships and character's development. For example, Heat is now the captain's precinct, and besides some paragraphs, there's not much into it. Or conflict between the Roach, it was not adressed fully and it would have been good to know more about them and the dynamic.
I also must say, regarding Rook and her relationship with him, that I was expecting something else... I mean, last book (spoiler?) ends with Rook proposing to Heat and we don't know what she says. And this book starts with a case and we barely see anything regarding them as soon-to-be-married. Yes, she has doubts and she's trying to sort them out, but then the usual problem between them (he's hiding something because of work, she gets angry and explodes... It's the seventh time we read the same issue). (SPOILERS AHEAD) I must say tho that Rook's abduction was new. And also, the wedding at the final scene was cute.
It's an okay book. Just wished more depthness.
