In The Plains of Passage, orphaned Ayla and wandering Jondalar search for a place on Earth they can call home.

Ayla and Jondalar set out on horseback across the windswept grasslands of Ice Age Europe. To the hunter gatherers of their world--who have never seen tame animals--Ayla and Jondalar appear enigmatic and frightening.

The mystery surrounding the woman, who speaks with a strange accent and talks to animals with their own sounds, is heightened by her control of a large, menacing wolf. The tall, yellow-haired man who rides by her side is also held in awe, not only for the magnificent stallion he commands, but for his skill as an artificer of stone tools, and for the new weapon he devises that makes hunting less perilous.

In the course of their cross-continental odyssey, Ayla and Jondalar encounter both savage enemies and brave friends. Together they learn that the vast and unkown world can be difficult and dangerous, but breathtakingly beautiful and enlightening as well.
