I love the concept of these books. Richard Castle, a fictitious mystery writer on the TV series, Castle, tags along with Homicide Detective Kate Beckett when investigating murders to get ideas for books and learn more about police procedure. He writes a series based on Kate, calling the character Nikki Heat. All of the characters Castle deals with on the TV show are showcased in the Heat series and they've released this fictitious series to us. His own character in the book, Jameson Rook, is an investigate journalist tagging along with Nikki Heat. They take it so far as to have the author of the book listed as Richard Castle.
This third book is a very involved mystery with so many pieces to it you wonder how it'll all pull together. But it does at the very end. It starts with the death of a priest in a sex torture club and takes you into areas and directions that totally surprised me. You'll love Nikki Heat who does her best to be true to herself even when politics become involved and she's offered what most people would gladly accept. The other characters are also well done and add a great deal of spice to the story.
The story is filled with a lot of action, twists and turns, relationships, tension, non-explicit sex and a just flat out wonderful mystery. I very much enjoyed the first two books, but this one is the best so far.
You don't need to watch the series to read these books. It's just a little more fun when you can put faces to the book's characters. I'd dearly love to know the actual author's name to see what else they've written.
