Andy Moor, a CIA agent with a serious case of burnout, realizes that a break from the stress of her job is in order. So she decides to visit her sister. At Christmas. In New York City. As if that isn't enough to tell her that her brain is too worn down to make good decisions, she agrees to go shopping in Times Square, a week before Christmas. When a body lands at her feet she's almost relieved. Here, finally, is something she knows how to handle. That is, until she realizes that the dead guy is her former CIA trainer. Now she has a lot of questions. And the cop in charge of the case, NYPD Detective Jack Stone, keeps looking at her sideways. Cops and CIA rarely mesh well. Andy will have to convince Stone that she's not involved in his case, professionally, or he'll clam up and not play nice in the investigation. When another body turns up, this one with no connection to Andy or the CIA, Detective Stone relents enough to read Andy in on the case. The more time they spend together, the more Andy realizes Stone isn't a moron. She actually kind of likes him. Dating a cop in the middle of what's becoming a serial killer investigation might not be wise, but Andy makes a living by taking risks and sticking her neck out. As she closes in on the killer, she'll have to be careful not to stick her neck out too far. The killer knows she's on the hunt and he's looking to turn the hunter into the hunted.
