This first volume was released 13th July 2018 by Grove Atlantic. It's 448 pages and available in hardcover, paperback, ebook and audiobook formats.
History is not normally my first genre choice. This one, however, was very well written and after a slow start, was paced and plotted well. The intrigues and power-jockeying at court were so clearly described that they were almost uncomfortable to read in several places.
Historical fiction lovers will really find a lot to like here. I will pick up the next novel in the series and I did enjoy this one, though I had to look up some of the back-history myself.
