Fair warning - the author is my brother.
After many years I was finally offered a prerelease version of Alberensa. Frankly, I was captivated. One of my favorite books is "Pillars of the Earth." Different time, different location, but the same rich texture of history with interesting and intriguing characters. What does one do to hang onto a small but critically important hereditary family holding when the very powerful want it for their own? Lots of twists and turns and a wonderful ending. I think you will enjoy it.
