Catherine Crook deCamp & L. Sprague deCamp 
Incorporated Knight [EPUB ebook] 

It’s never easy being a knight, especially for a practical Eudoric Dambertson, whose mind and temperature are better suited to trade than to the highly impractical demands of chivalry. Take the simple matter of courting a wife. To please his potential father-in-law, the enchanter Baldonius, the young man must bring back two square yards of dragon hide. Only then can he earn his knightly spurs and the hand of the beauteous Lusina. But battles with dragons always seem to go better in the ballads.
