Description of Dragon Knight by E.Y. Ryks
Cor the dragon has a problem; he's bored. As a way of amusing himself, he convinces his princess, Espreta, to help him become a knight. No sooner than he does his first heroic deed, Cor is sent by his fellow dragons to rid them of a dragon's bane (nemesis). Cor doesn't find it easy to secure the trust of his new found friends and the dragon's bane, with ties to Cor's past, has no intention of giving him the chance.
