Oh, then that's a fair question. T.A. Pratt is actually Tim Pratt, but the Marla Mason series (at least 2 books into the series) isn't the pseudo-erotic series that (from what I've heard) the Anita Blake novels are. Granted, in one of the books, Mason encounters a sorcerer who derives his powers from sexual energy, but that's more to show the variations on deriving magical power rather than blatant sex. Mason also encounters a character who is very charismatic, but again, not quite like what you've probably seen in Anita Blake.
Put simply, sex is a part of the stories, just like anything else and it isn't the only driving aspect of the stories.
I stopped reading the Anita Blake novels at about the 4th or 5th book and so far, I'm not seeing any signs of me stopping the Marla Mason novels, the third of which (Dead Reign) is due out in October.
