O'Brien de Clare, T. J.: - TJ O'Brien lives in the wilds of the Yorkshire Dales with his wife, Sam, who takes a cynical approach to his historical interests. Although he has produced technical manuals in relation to his career as a cyber-security consultant and has helped with translations and maps for several other Helion publications, 'Une Foy, Une Loy, Ung Roy' is his first published historical work. He studied for his Masters in Military History at the University of Leeds, where he gained a Distinction and won the Marion Sharples prize for his dissertation. When not reading or writing, he practices archery, wanders in the woods, plays games and mentally designs steam-powered airships.
