The Wild Shore

When did you first have the idea for the wild shore? And then let me set it up for the listeners a bit. The trick of these novels, the introduction in the tour book three California's by sprains, the stuffer, you know, described as a a triptych. It is three different futures in California are really Southern California, Orange County, that are all the same and all incredibly different. So the first one is the wild shore, but I'm wondering, was it a trilogy? Was it a triptyCh to begin with?
