First time in paperback from the New York Times bestselling author of Monkeewrench.

Computer game experts Grace MacBride and Annie Belinsk are en route to Green Bay following reports of a serial killer when their car breaks down deep in the northern woods-and near an eerily quiet town where the phone lines are dead and no one is in sight. But when they witness a double murder, they find themselves running for their lives....

When the corpses of three police officers are discovered entombed in snowmen, Grace MacBride and her team of crime-busting computer jocks at the Monkeewrench firm are called in to assist. What they discover is a terrifying link among the victims that reaches beyond the badge and crosses the line between hard justice and stone cold vengeance....

People are dying for the new computer game by the software company Monkeewrench. Literally. With Serial Killer Detective out in limited release, the real-life murders of a jogger and a young woman have already mimicked the first two scenarios in the game.

But Grace McBride and her eccentric Monkeewrench partners are caught in a vise. If they tell the Minneapolis police of the link between their game and the murders, they'll shine a spotlight on the past they thought they had erased-and the horror they thought they'd left behind. If they don't, eighteen more people will die......
