Alaskan charter pilot Norm Lewis has been missing for months when the spring thaw reveals the ruins of his missing plane. But the corpse inside, beaten to death even before the final bullet, isn't Norm's: It's the body of a woman, a federal agent who vanished during a sting operation against poachers in the Arctic National Wildlife Refuge. Rochelle Lewis, convinced that her husband must have tried to walk from the plane to the nearest settlement 30 miles away, flies out to follow in his footsteps- -and she does, in more ways than one. Luckily, featureless State Trooper Alex Jensen (Termination Dust, 1995, etc.) is on hand to rescue Rochelle from the transparent bad guys and pull together the scant loose ends. More frigid adventure than mystery, though the Alaskan snapshots may satisfy less demanding fans of John Straley and Dana Stabenow.
