As winter closes in, a deadly game begins ...

With tensions at an all time high, the team is divided, pulled in different directions as they hunt different prey. Jamie doesn't know which way to turn, but when the killings begin, things become blindingly apparent. They're not just dealing with a killer doing this out of necessity, but one doing it out of pleasure. He's skilled, experienced, and he knows who is chasing him, and seemingly, how to avoid them at every step.

Can Jamie outwit a killer who's been trained to beat her? And can she kept her nerve as the stakes grow ever higher? With old friends and new enemies swarming around her, this is Jamie's toughest case yet, and will push her to the breaking point. She'll need to call on all of her experience, and all of her contacts, if she hopes to win this fight. But, even if she does, what will it cost her?
