Jack O' War

Jack had survived great perils as a boy, and more as a guard at Dudley Castle. But the sowrd-wound that he'd sustained rendered him fit only for a desk-job and cooking.
Bored with the humdrum work, and dissatisfied with his marriage, he enlists as an archer in King Edward's army.
But this time, in addition to the human antagonists, he encounters others from the realms of Magic, Saints and Demons.
How will he meet these latest challenges?
