Darkwitch Rising — Sara Douglass

BRITAIN. AN ANCIENT LAND.
Most think they know its history--but few know the truth.

From the mists of time came Brutus, last of the Trojan kings, armed with hidden knowledge. He was captivated by the alluring sorceress Genvissa and together they almost succeeded in creating a magical Labyrinth that could rival the might of the gods. But the Labyrinth was struck down by Brutus's wife Cornelia, who believed that to challenge the power of the gods was to destroy the world.

Her actions trapped them in an endless cycle of death and rebirth. Ages passed, and time and again the players came close to victory, only to be thwarted each time.

But these soul travelers have arrived in a most unique Now: the English are at war, a mighty Civil War that threatens to destroy a nation. A great pestilence is upon the land, and the newly restored Charles II is trying to hold chaos at bay. He is another player in the game, reborn yet again...

And he is not alone.
