Teenager and his mother moved to a new city (in Arizona, I think). Teen likes to jump from airplanes for sport. Younger girl at the airport (possibly the owner's kid) has a crush on every new guy that comes along. Teenager jumps in tandem with a group of other sky divers. I think the kid's nickname was "Wraith".
Unfinished, abandoned, and no-one seems to know whether the author died while practicing what he preached (jumping out of perfectly good airplanes) or if there was some other reason why he stopped.
There was a 16 month gap between the last two chapters he posted which is the best indication he did not die in an accident.
