The Shelters of Stone, by Jean M. Auel

I am currently reading The Shelters of Stone by Jean M. Auel.  This is the fifth book in the continuing series of Ayla and Jondalar.  In the last story, they completed their trek across Europe to Jondalar's home.  Now they have arrived and Ayla is in awe of their clothes, customs, language, and even their homes.
