Somebody is killing people who work for subsidiaries of conglomerate
Ault Enterprises and playing some kind of game while doing it. Carol
Golden is called on to help identify the killer because she has
experience in breaking codes and playing games. Amy O’Connor, a
former scam artist and long-distance hiker with an eye for men,
becomes her partner by accident, and together they search for clues
in interesting places. The hunt takes them to the tops of significant
mountain peaks in the United States, including Mount Whitney, the
highest peak in the continental U.S., and to other unusual locales
such as the thinly populated Lost Coast region of northern
California. Carol finds that incidents in her past that are lost
to her because of her amnesia may come back to haunt her before
she can win this deadly game.
