Dave Duncan 
Demon Knight 

Longdirk, the hero of medieval Europe, faces his greatest threat. “Duncan excels at old-fashioned swashbuckling fantasy” (RT Book Reviews). The Scottish outlaw Toby Strangerson, known as Longdirk, has used gramarye, dark magic, to defeat the Fiend and save Europe from abject slavery—but he has also made himself the most feared and envied man in all of Italy. The hordes are reorganizing and plan to sweep over the Alps once more and retake their lost prize of power and conquest. Toby and his friend Hamish struggle to unite the quarreling city states into a single, powerful force to resist the invasion in a world where no ally can be trusted and traitors lurk in every shadow. But there is more at stake than freedom and the destiny of a continent. A woman’s love is also hanging in the balance. This book was originally published under the name Ken Hood.
