WTF?? Did you know that the books on the TV show "Castle" are real books?? Here's "Naked Heat" by "Richard Castle," who looks surprising like Nathan Fillion...
There's also "Heat Wave," which, umm, Tina already made me buy BTW. I'm going to have to wrestle her for it, I think. But here it is anyway.
