West of Eden Trilogy

Kerrick's tribe, which includes the two male Yilane who have elected to remain with him, live an almost idyllic life away from both the Tanu and Yilane.

The scientist Ambalasi studies the primitive Yilane, in between solving the problems involved in getting the Daughters of Life to work, since they are all regarded as equal, so none may lead the work force. The battle of wills provides for several humorous exchanges.

The other Tanu tribes eventually meet up with Kerrick's. While Vainte makes her way along the coast to a Yilane city. She persuades the leader there to let her lead a group in search of the Daughters of Life, secretly planning to seek out and kill Kerrick and the other Tanu.

The weapons the Tanu stole from the Yilane begin to die. Without them, they won't be able to kill the larger dinosaurs which threaten their safety this far south. But Kerrick eventually comes to terms with the fact that he is Tanu and not Yilane, renouncing their ways, and finding a solution to their problem with the skills of the different groups of humans he has contact with.
