There must be twenty chariots out there . . .He glanced at Oolou, shouting. She stared back at him with a ghastly grin, the blood pouring from her neck above the corselet where an arrow stood, stark and brutal.The Chariots of Ra is a parallel worlds adventure novel, set in Kenneth Bulmer’s 'Keys to the Dimensions’ series.
