'Promise of the Wolves' tells the story of Kaala, a wolf cub born in an interesting time and place. It is 14,000 years ago in Europe, and the beginning of the association between wolves and humans that will eventually lead to the development of man's best friend, the domestic dog. The wolves are forbidden from consorting with humans, but Kaala rescues a young girl from drowning and finds that she cannot stay away from her new friend. She soon leads some of the other wolves into friendships with humans, with consequences that, legend says, could either save or destroy wolfkind.
Unusually for this type of book, 'Promise of the Wolves' is written in the first person. This is a clear attempt to pull the reader more firmly into the story, but it has to be said that it doesn't quite work - Kaala often uses human terms and ideas of which a wolf would have no knowledge. The wolves can also understand human speech, and some of the humans can understand them in turn, which is a little too fantastical for my taste, though it may appeal to younger readers.
The book also contains some factual errors. It is obvious that the author has observed wolves, but she has misinterpreted some of their behaviour, either from lack of understanding or as a deliberate plot device. For example, the wolves in the book are drawn to humans instead of being afraid of them as real wolves are, but of course this is necessary given the story. Worse, at least in my opinion, is the cruel way they often treat each other in this book. Wolves are strongly bonded to the other members of their pack and take care of their weak and sick - in 'Promise of the Wolves', however, weakness is not tolerated, and even cubs are routinely denied food, left vulnerable to predation, or even killed. This would never happen in reality - offspring are simply too valuable to risk, and are protected at all costs. Something else that particularly irritated me was the fact that, though the book is set in Europe, it features animals that only ever lived in the Americas, such as dire wolves and Smilodon.
I am very surprised to see so many people mentioning Jean M. Auel's 'Clan of the Cave Bear' and its sequels in reference to this book. Aside from both being set during the Stone Age, the two have nothing in common. Auel's books are generally well-researched tales of ancient humans, aimed clearly at adults - these books can be quite explicit and are not suitable for children. The heroine, Ayla, does begin to domesticate animals in the second book, but this is by no means the focus of the story. At no point to do animals and humans speak to each other and everything is from a human viewpoint. 'Promise of the Wolves' is a children's story of talking animals, in which the entire plot deals with wolf-human interaction.
In conclusion, younger readers or fans of wolves who are after fiction and fantasy rather than fact may well enjoy this book. However, older readers and those with a good knowledge of wolves and/or their domestication will find 'Promise of the Wolves' a little too far-fetched, and may be put off by the factual errors and eco-friendly message, which, whilst commendable, is laid on a little too thick.
