First things first, Richard Castle is not a real person. He is a fictional character from abc's Castle (shown on Alibi in the UK, see review elsewhere here) and the book has been ghost written entirely in character based around Castle's involvement with the NYPD.
The novel has Jameson Rook (Castle, get it?), a journalist, shadowing Detective Nikki Heat as she attempts to solve the murder of a Real Estate millionaire.
This is just like reading an episode of the show and it's good fun for fans but isn't likely to appeal to anyone else.
The writing is cheesy and shallow, just like the Castle character would write and there is some nice humour thrown in.
An undemanding read recommended to fans of the show.
