Query: Boring! Long-winded! Very little plot!

What is she doing to this series? Clan of the Cave Bear was magnificent. Valley of the horses was interesting. Mammoth Hunters was tantalizing. Plains of passage was barely entertaining. This book is even less entertaining. She doesn't answer questions. What happened to Durc? Surely there is a lot more to his story and the flatheads then this. Surely, there has to be more going with the original clan. I mean, where is the story? She just rehashes everything again and again and it takes pages and pages and pages to get any plot. She is slow writer and I can't believe I waited this long for this thing. I feel like a flathead for actually reading this thing.
