THE BODYGUARD it ain't. Imagine the same kind of sparse tone of Q&C applied to the bodyguarding industry and you're pretty much where the AK series is. SHOOTING AT MIDNIGHT, especially.
(CRITICAL SPACE I found a little disappointing, as it goes. It's a page-turner, all right, but the character work was a bit sketchy and the core concept is weaker than pretty much all the others. But then again, I really didn't like the ending, and that may have utterly coloured my perceptions.)
Have you read WHITEOUT? That's pretty cool (and ISTR the sequel, WHITEOUT: MELT, introduces a character called Lily Sharpe, who may or may not be a work-in-progress version of Tara Chace).
