Lyonesse Book 1

The Lyonesse sequence evokes the Elder Isles, is a baroque land of pre-Arthurian myth now lost beneath the Atlantic, where powerful sorcerers, aloof faeries, stalwart champions, and nobles eccentric, magnanimous, and cruel pursue intrigue among their separate worlds . . .Prince Aillas of Troicinet is betrayed on his first diplomatic voyage and cast into the sea. Before he redeems his birthright, he must pass the breadth of Hybras Isle as prisoner, vagabond, and slave, an acquaintance of faeries, wizards, and errant knights, and lover to a sad and beautiful girl whose fate sets his bitter rivalry with the tyrant Casmir, King of Lyonesse.
