Squall by Sean Costello

Dale Knight was just supposed to drop off the drugs and pick up the money. Instead, his girlfriend, high on coke, kills the drug dealers and steals both the drugs and the money. The pair flee to northern Ontario to hide out in a winter cabin. But killers are closing in.

Tom Stokes, a flying-in operator, crash lands during a winter blizzard and suddenly both he and his family are drawn into a deadly game where a mistake gets them killed. Costello takes on one hell of a ride.
