This is the fourth book in the series and sees the two leads make an epic journey home across prehistoric Europe.
I loved the first book in this series and the second one was pretty good too, but it seems that as the series goes on the author struggles to find enough "story" to write about so spends half of her time writing exessive descriptive passages that I have to admit I only skim read until there is more character interaction. Approximately half of each chapter seems to be an in depth account of the geology, flora or fauna of the region - whilst this is informative it does not add anything to the story and the already vivid pictures created in the readers head, making the book longer than necessary. The author seems to need to prove that her work has been meticulously researched when really she doesn't need to, it is obvious anyway, and sadly this sometimes makes her novel seem like a textbook (having just finished Uni I was hoping for an escape from this!).
Another gripe of mine is that the main character Ayla and her boyfriend Jondolar just get more and more perfect and one dimensional with the passage of time, they are always right, no one else can have an opinion and what started out as deep characters are getting shallower and more predictable with each book. They are both gorgeous, morally sound, great in bed, everyone they meet loves them immediately or pretty soon after Ayla has wowed them with her amazing skills of magic, healing, animal taming, inventing the wheel..... (ok so the wheel one was a joke but you get the idea). I would have liked to see some character flaws to make Ayla more "real" as she is becoming more and more god-like in her perfection.
Having said this I can't leave a series unfinished and as a bit of escapism it can be enjoyable so I am currently sarting Auel's 5th one.
