I can't write a review for this book because everything that needed to be said about it has already been said. So just go read Kevin Fanning's review instead.
(Except that I lied, because one thing Mr. Fanning did not say is that Naked Heat is several steps up in quality over it's predecessor, Heat Wave. The roman à clef thing didn't bother me at all in this one. The characters are beginning to take on a life of their own, which is a very good thing.)
