I have loved the TV show Castle and so when I discovered that there were actually books, I jumped straight into them.
This was a great book. I loved that Nikki and Jameson are in some ways totally different to Castle and Beckett, but in others exactly the same. I love Roach and their interaction with each other. The storyline was completely in line with anything you would see on the show Castle. But you don't have to watch the show to get the books. It can be one or the other, or both. And that's great.
