Lion's Blood

The year is 1279...or, to those who worship the son of Mary, 1863. Bordered by fierce Azteca to the south, the red men's nations of the far west, and the Viking empire in the north, Bilalistan is a vast, rich land adorned with inspiring mosques, Zulu kraals, and glorious Moorish castles. Its grand estates are worked by savage Franks and Gauls captured from darkest Europe.
A primitive child from Eire, little Aidan O'Dere knows nothing of the world on the day his village is raided. His father is murdered while Aidan, his mother, and his sister are chained in the dark, diseased hold of a slave ship bound for the New World of Bilalistan. There the boy is sold to Dar Kush, the estate of the Wakil Abu Ali.
The Wakil is notorious for his lenient handling of his whites, even letting them keep their tribal names and pagan beliefs. And when Aidan becomes personal servant to the Wakil's mischievous yet brilliant son, Kai, friendship is allowed to blossom between the two youths - a bond that seems to eclipse their status as master and slave. But the tranquillity of Dar Kush hides a world where slave families are torn apart to pay bets, whipping and rape are daily fare, and runaways are slaughtered by vicious animals. And behind their happy comportment, the whites are seething with hatred.
When war suddenly sweeps over the entire continent, the Aztecs, Zulus, Arabs, and whites are engulfed in carnage. And in the terrible darkness of the battlefield, Kai and Aidan will learn that blood is neither black nor white.
