Not long after his wife, Trish, died from driving 90 mph on 101 without tapping the brakes, husband Pat Moore's friend, Rick, receives a chain letter he wants to forward to Pat for luck. Pat refuses but strange events do happen, such as a traffic accident where the ghost of a different Pat Moore appears in his car, claiming to protect him from yet a third Pat Moore who's coming after him.
The guardian angel, Pat suspects, is someone who had been very near and dear. Pat, a gambler, has to make some gambles on his life to save it. There's a cool allusion to Maxwell's demon. I love funky science.
This is a story of not leading the life that others and the past saddles but rather accepting your life, however long or brief it may be, and being ready to take a gamble now and then. The story is more simple than it may sound, except for a raising scene that I didn't quite get. It's pure Powers, wild, weird, and wonderful.
