Announcing Sacred Mounds, a novel of Magical Realism and Historical Fantasy from Jim Metzner, with a foreword by Hutke Fields, principal chief of the Natchez Nation.
Cyclonic hordes of insects, a telepathic despot, body-swapping sex - just a few of the surprises Salvador Samuels encounters when he is swept back to pre-colonial times, walking in the moccasins of a blind Indian - who, in turn, has been transported into Salvador's body in present-day America. Sacred Mounds Book Cover Four hundred years apart, they are bound by a mission to rescue our world, aided by the mysterious presence of the mounds. Thousands of these ancient earthworks once dotted the landscape of North America. We still don't know why they were created. Sacred Mounds suggests they are as important today as when they were made over a thousand years ago. Sacred Mounds weaves the stories of two men, each a stranger in a strange land. With the help of two remarkable women, they must find a way to save our planet and return home.

Dogs and humans have changed each other in many ways over the years... perhaps for the better.

BH: The DNA inside your dog is almost identical to the DNA or code inside of a wolf. And what that told scientists is that actually dogs, long ago, they were actually wolves.

JM: Over thousands of years, dogs have changed, evolved, as a result of their contact with humans. Well, have we changed as a result of our contact with dogs? I'm Jim Metzner and this is the Pulse of the Planet. Brian Hare is an evolutionary biologist at Duke University.

BH: So, you can ask how is it that dogs ended up the way that they are? It ends up that the dogs that were with us were really the least aggressive of all the wolves. And if they were peaceful and if they were tolerant of people well then they got to stay with us and they became dogs. Well what about humans? Does that mean that dogs have actually changed us somehow? Well one of the ideas that people are thinking about is, yes! Dogs actually have changed us. Because dogs are very, very good at alerting us to danger. And it made it easier for us to live in large groups together but more importantly than that- the other thing that dogs helped us do is we had to be peaceful towards other animals. Because if we wanted dogs to help us by barking and alerting us to danger well we had to be nice to the dogs. So in some ways while dogs had to become less aggressive to live with us we also had to become less aggressive and more peaceful towards them. So we've really changed together and we have both become more peaceful.
