Krono — Charles L. Harness

On an ecologically seared Earth, James Konteau is a veteran krono, a professional time traveler. His job is to ease the overpopulation crisis by establishing new colonies in Earth's prehistory, long before human beings evolved. But his job has lost all meaning, for Konteau is a lone and troubled man haunted by his own past.

Now, suddenly, his future is also in turmoil: a timequake has reportedly ripped through distant eons, destroying one of Konteau's colonies. Framed for the disaster, Konteau is hunted by authorities, defying all the powers of technology and politics to escape back through the misty ages on a complex mission of death, justice, love - and incredible destiny . . .
