Song of the Earth
by John R. Dann

Description:
The powerful daughters of River Woman saved young Grae from a flooded river after a volcano erupted and destroyed their tribal home. Then they made him chief, but that's almost the last thing they agree on before the tribe splinters.

Grae leads the main group out of Africa ever northward, into central and eastern Europe, always searching for safety and a better life. Challenged by truly monstrous evil tribes, but guided by spirits, they survive. It takes three generations, and three chieftains named Grae, before the tribe comes to rest.
