I've recently gotten into a few books by
Sharon Kay Penman, mainly her Welsh and English trilogies.
The English trilogy begins with When Christ and his Saints Slept, then Time and Chance, and Devil's Brood. It begins in the 1100's with the war between King Stephen and his cousin Matlida for the throne of England. It follows with her son Henry II taking the throne as Stephen's heir and his reign and marriage to Eleanor of Aquitane (one of my personal heros) and then on to Henry's conflicts with his sons, Henry, Richard, Geoffery, and John, finally ending with John on the throne of England.
The Welsh Trilogy starts with Here Be Dragons, then Falls the Shadow and The Reckoning. This series starts in about 1183 with the story of Llewllyn Fawr, prince of Gwynedd, Wales and his marriage to Johanna, illegimate daughter of John, and ends with his grandson Llewellyn ap Griffydd, the last prince of Gwynedd conquered by King Edward about 100 years later.
There is a bit of historical discrepancy moving from the English trilogy to the Welsh due to the fact that the Welsh was actually written first, and the author had done more research, mainly on Richard and Eleanor, by the time she wrote the English trilogy. She does an excellent job making the characters seem real and not just another story from a history book. Since reading the books I have also had the chance to correspond a little with the author, and in a bit of a round about way been also introduced to a very nice lady who owns and maintains
Garth Celyn, which was the main residence of the princes of Gwynnedd. My only reget is not having these books to read when we were actually stationed on that side of the pond and visiting a lot of these places was much more of a reality. I have been to a few of the places in the stories, but the majority of the history that is presented to the public is that of the Tudor's, and not so much of the Plantagenets and almost none of the Welsh.
