Storm of Century correct.
{B]Barrk,[/B] I think "Storm of the Century" or something similar was the name of a movie based on a Stephen King (I think) novel. I saw the movie, but never read the novel. My gut feeling was that the movie probably followed the book fairly well.
I read more Dean Koontz that King, but think I have a feel for King's style. Koontz is great: I have read everything he has published.
The Omerta story is still eluding me. I play serious tournament bridge, and encounter some people who read a lot at the bridge table. I have been asking some and them, and have gotten no replies yet.
If I find the author or other data, I will post it here. When all else fails, I will try an Internet search for Omerta, and also some searches for Sci-Fi authors (It sounds a bit like Sci-Fi or fantasy fiction).
One of my bridge friends claims that "Omerta" means death or silence (possibly both) in Italian. She was not certain, merely said it seemed correct to her.
