Wales

A compelling story of war, love,
and magic. It is the year 1400 and Wales is on the brink of a bloody
revolt. The unlikely figure of Rhisiart, a young Oxford scholar, becomes
entangled with Owen Glendower, the last true Prince of Wales.

The story of Llewelyn, the first true Prince of Wales, is the story of
medieval Wales in dramatic and epic form.

These books were published together in a single volume, also separately,
as, in order:
Sunrise in the West
The Dragon at Noonday
The Hounds of Sunset
Afterglow and Nightfall
