Synopsis Says It
The blurb is accurate, but it's also a fun read. If you like vamping it up in online RPG's you'll probably enjoy this book. Watch out for undercurrents of early twentieth century sexual morality, however, in the development of the main characters. Without doing any serious research, I would say that 14th century individuals might have reacted to issues of fidelity, property rights, and class structure somewhat differently than portrayed.
A novel, after all, not a biography, and still a great escape!
