The Last Change Killed Off The Dinosaurs

The Earth's magnetic field is overdue for a dramatic change that may have repercussions for every living creature on the planet.

The event, in which the north and south poles reverse positions, is referred to by scientists as the "magnetic polar shift." It usually occurs every sixty million years, but is now five million years overdue.

Just how this extraordinary event will impact life on Earth is unknown. Given the timing, the last polar shift may have killed the dinosaurs-or at least contributed to their demise.

Author AJ Scudiere explores this important dilemma in the much-anticipated new novel Resonance. It's the story of four scientists who uncover the Armageddon-like effects a massive polar shift could cause-and live to tell about it.

"Although this book is fiction," says the author, "the science behind its premise is not. The leading theory states that small areas shift polarity first. Once these areas reach critical mass, the poles 'snap,' instantaneously trading places. The problem is that we have no idea what the effects will be."

In Resonance, the town of McCann, Tennessee, becomes the first "hotspot" affected by the shift, and as the four scientists come to discover, it won't be the last.

Some of the major turning points in Resonance eerily echo real-world events that some scientists believe portend the upcoming shift:
