Who is making the crop circles?

The enormous geometric designs have appeared in fields around the world for over thirty years. Novelist Risa McKensie plans to write about the fantastic works of art. When her intent becomes known, she receives an anonymous warning to drop the project. She can't imagine why. Because a fiction book might become a bestseller and draw attention to the circle phenomena? Who would care? Clearly, when the warnings multiply, more than one group.

Risa meets a group of intellectual Artists who claim they make the formations using mental energy. Despite the escalation of the threats, she discounts the Artists' advice that The Meridians--a powerful consortium that thrives on war and chaos--are the ones she should most fear. Why would a novel about crop circles concern them?
