Well, no, not exactly. It's a book, not about heraldry, but about heralds. Specifically, The Herald in Late Medieval Europe.
This book is available from Boydell & Brewer, and costs US$95.00 or £50.00. More information about the book, its authors, and links to order it, can be found at http://www.boydell.co.uk/43834820.HTM
