Quinton Mann is CIA through and through. Mark Vincent is WBIS for life. There is no way they could end up as anything other than adversaries -- and yet, Quinn takes Mark out to dinner on his birthday -- the one no one is supposed to know about -- and gives him one hell of a present in the restaurant's restroom. Mark, not to be outdone, has decided to escalate this game, because it has to be a game, right? There's no way it can be anything else.

But as the game continues, as Quinn shows up to a WBIS funeral, as a friend of Mark’s penetrates the CIA computer network to get information on Quinn, as Mark breaks into Quinn's house and gives Quinn a very interesting encounter, both Quinn and Mark realize that this is becoming the most real thing in their lives.

Can they find a way to do their jobs and keep this surprising, intriguing connection?
