Black Horses for the King

From the bestselling author of the Dragonriders of Pern series comes this historical fantasy of King Arthur as it has never been told before. It is the story of the beginnings of the British cavalry, as recounted by a boy growing up in exciting and perilous times.
Galwyn, the son of a bankrupt and dishonored aristocrat, has always had an ear for languages. So when Lord Artos--later known as King Arthur--needs an interpreter to help him buy large horses to breed a troop strong enough to carry armed warriors against the Saxon invaders, Galwyn gets a chance to redeem his father's honor and make a name for himself.
