The Peel Affinity does not disappoint. From a physical point of view, it is nicely bound with a handsome dust cover, a silk ribbon and slick paper with color photos on almost every page. The introduction says:
The book is divided into three sections. The first is a brief introduction to the world in which our characters live. In the central part, we take you through a year in the life of our fictional English knight and the people around him. The last part presents a more generalized view of campaign life and war as they might be experienced by our characters. Throughout you will find sidebars highlighting important aspects of medieval English life which affect the lives of our characters.
The book is provided by a historical recreation group called La Belle Compagnie, and depicts the band's impression of a late 14th century knightly family, that of Sir Geoffrey Peel. The photos are gorgeous, in places stunning (some interior room scenes at spots like pp. 40-1, for example). I haven't had time to read the book, but at a glance the text seems quite serious and accurate.
I'll have more comments later, after I've had more time with the book, but I'm delighted with the purchase.
Update: Oops, I missed the link to buy on this page, too.
