The Magefire by Alexander Baliol

I read this book in 1990 when it first came out. It is an excellent fantasy novel whoch I enjoyed hugely. It ended in the middle of a huge battle, as it was the first part of an intended trilogy. And that was it. I have nver seen any other book by Baliol, let alone then next in the series. Google turned up a second book in the series - The Tears of Ginara - but I can’t get beyond that.

So, my question, does anybody else know anything more than I do?
