Bullets of Rain — David J. Schow

Widowed architect Arthur Latimer has become a recluse in his own home: a storm-proof fortress that doubles as a shrine to his dead wife. But the outside world beckons in the form of a bizarre party downbeach.

Now, just as the biggest hurricane ever to hit the Pacific Northwest rolls in with deadly force, Art is subjected to intrusions from his past and invasions from the present. And soon he begins to doubt everything he sees or thinks he already knows. And soon you may too.
