By A.D. 2110, nearly 100,000 humans had fled the civilized strictures of the Galactic Milieu for the freedom they thought existed at the end of the one-way time tunnel to Earth, six million B.C.

But all of them had fallen into the hands of the Tanu, a humanoid race who'd fled their own galaxy to avoid punishment for their barbarous ways. And now, the humans had made the Tanu stronger than the Firvulag, their degenerate brethren and ritual antagonists. Soon the Tanu would reign supreme. Or so they thought...

In this second installment of the Saga of the Pliocene Exile, a small group journeys through a time-gate into Europe's prehistoric past. Yet this supposedly unspoilt sanctuary holds two alien races locked in combat. In a world where the human-like Tanu have the upper hand, Elizabeth Orme soon encounters trouble. When they find she possesses rare mind powers, they want her for their own. She won’t be used as a pawn in a Tanu versus Firvulag war, but Aiken Drum can’t wait to get involved.

Aiken discovers the Tanu’s mind-enhancing torcs have given him his own powerful abilities. And it’s not long before he devises a plan to challenge the Tanu’s leader – for rule of the Many-Coloured Land itself. But another faction seeks the slaughter of all humans, and he stands in their path.
