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.

music; ambience paper crumpling

JM: There’s a reason we crumple paper before tossing it into the recycling bin; it’s a good way to counter earth’s dense air pressure. Try tossing an uncrumpled page, and it’s not going to make it to the basket. But toss a paper-ball on Mars, and it’ll really go the distance. I’m Jim Metzner, and this is the Pulse of the Planet.

AV: “When we want a ball to go really far and really fast, we make it really small, like a golf ball. On Mars we could play golf with even bigger balls because they would see the air less. They would notice it less and be able to go just as far into the hole 300 yards away.”

JM: With low air pressure and minimal gravity, Mars just might be the ideal playground for all kinds of sports, if we ever colonize the planet. Ashwin Vasavada is a planetary scientist at NASA’s Jet Propulsion Laboratory. He’s also a participant in our latest edition of the Kids’ Science Challenge, a nationwide competition for 3rd to 6th graders. And Imagining Sports on Mars is one of this year’s entry categories.”

AV: “All of the sports equipment that we use on Earth are really kind of tuned to Earth’s atmosphere. Things are affected by the wind, just like the paper. Different balls and Frisbees and things like that that are carried around by the wind in different ways, and all that’ll have to be sort of rethought and redone as we go to Mars. Frisbee is probably the kind of sports equipment that’s most tuned to Earth’s atmosphere. It’s basically like a wing. If you weren’t throwing it and it wasn’t flying through the air and being lifted by the air, it would just drop, but on Mars, where the air is so much thinner, Frisbee won’t work so well. It’ll probably just drop if we threw it normally like we do on Earth.”

JM: If you know a 3rd to 6th grader who can come up with an idea for a sport that’s tailored to the Martian environment, well, have them log on to kidsciencechallenge.com. That’s kidsciencechallenge.com.
