Did you know that the fictional author, Richard Castle (played by Nathan Fillion in the TV show Castle) has actually released three books in real life?
The novels Heat Wave, Naked Heat and Heat Rises have been released under the name Richard Castle as part of the promotion for the TV Show. In addition, a graphic novel entitled Deadly Storm, based on one of Castle’s earlier works was released by Marvel Comics in 2011.
Heat Wave made the New York Times Bestseller list, peaking at #6 in it’s fourth week of publication, while Naked Heat debuted at #7. Not bad for an author who doesn’t exist!
