I am trying to identify the author of a series of paperback SF books I read back in the 80's. The stories were written in the 80's or in the late 70's. (Or maybe I am remembering that wrongly).
The conceit was that a place like actual colonial Virginia was being settled (something like a few decades after the founding of the Jamestown colony), there was tobacco farming involved, and indentured servants. I think that the largest settlement was along the coastal plain. There was exploration to the mysterious and magical interior in the woods and mountains of what was obviously colonial era Virginia (1600's) with blunderbuss, musket, etc.
I vaguely recall some puritan religious sorts mixed in somewhere.
At one point, some of the major characters went into a mountain and magical stuff began to happen. I never found the next book, though.
I could swear that the author is named Angus {something scottish} but my internet searches to date are not working. And I also might be recalling the name incorrectly.
Who wrote these speculative fiction/fantasy novels?
What is the name of the series?
I can't find any of them up in my attic with all of my old Conan and Elric books, so I either lost them, donated them, or turned them into second hand books a few decades ago. It's killing me.
