A Knight from Dein, by Peter R Stone

A 521 page epic fantasy adventure.
Sir Carl Hardcourt, a merchant-knight from Dein, must make a difficult decision. Will he fulfil his obligation to build his father’s commercial empire and forsake his chance for courtly love? Or will he heed the call of chivalry and offer his sword to the King of Tenham, who is making a brave yet futile stand against the invincible hordes of grey-skinned, humanoid amalehqs, lead by their brutal king?
The Tenhamese Prince Terrance Whitgrave is headstrong and impetuous, but will face betrayal, terror, and dishonour beyond his comprehension. Can honour, once lost, be regained?
