No fixed line
(Book)

"'... though there is no fixed line between wrong and right, There are roughly zones whose laws must be obeyed.' ... It is New Year's Eve, nearly six weeks into an off-and-on blizzard that has locked Alaska down, effectively cutting it off from the outside world. But now there are reports of a plane down in the Quilak mountains. With the National Transportation Safety Board unable to reach the crash site, ex-Trooper Jim Chopin is pulled out of retirement to try to identify the aircraft, collect the corpses, and determine why no flight has been reported missing. But Jim discovers survivors: two children who don't speak a word of English. Meanwhile, PI Kate Shugak receives an unexpected and unwelcome accusation from beyond the grave, a charge that could change the face of the Park forever." --,Provided by publisher.
