No Fixed Line (Kate Shugak, #22)

…though there is no fixed line between wrong and right,
there are roughly zones whose laws must be obeyed.
—Robert Frost
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 NTSB (National Transportation Safety Board--responsible for investigating aviation incidents) 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.
