I have a boxed set of the first three Jean M. Auel Earth's Children books (The Clan of the Cave Bear, The Valley of the Horses and The Mammoth Hunters) in paperback.  They are all listed on my shelf individually, and I'll let them go if requested individually.  Just thought I'd put this out there in case someone is looking for a set.  

I also have The Plains of Passage in hardback. It's the fourth book and not a part of the boxed set.

If you do want to order the boxed set, you may want to check with me first to make sure I haven't sent any out individually.

Thanks!
