The happy author brandishing a copy of his new book on Verdun, posed in front of a small part of the book collection.
Just visible over his left shoulder are the spines of two of his previous books, They Shall Not Pass: the French Army of the Great War and Kings of the Air: French Aces and Airmen of the Great War, both published by Pen & Sword, not only as hardbacks, but also in Kindle and ePub format (links to the P&S website).
