When Peter Ash receives a phone call at four a.m., it's the start of a dangerous whirlwind that leads him into the criminal underworld.

Lewis has a criminal past that he's put behind him. He’s also Peter Ash’s closest friend, and he’s helped Peter out many times. So when he calls unexpectedly, asking for help, Peter knows things are serious.

An old criminal associate of Lewis's has gone missing from his home in upstate Wisconsin. There's blood on the snow, a burnt-out cabin – and a blizzard to contend with.

As Peter and Lewis search for answers, they discover something else is missing: notebooks with evidence of Lewis’s past crimes. Evidence that greatly interests some seriously dangerous criminals… killers who are willing to wipe out Lewis’s family to get what they want.

Soon, Peter is in a race against time to find that evidence – and stop the bloodshed before it's too late.
