Angels Don't Play This HAARP: Advances in Tesla Technology (1995) by Dr. Nick Begich and Jeane Manning argues that the U.S. military's HAARP facility is a covert, advanced weapon system capable of weather modification, environmental disruption, and mental manipulation. The book contends that by using high-frequency radio waves to manipulate the ionosphere based on Tesla's theories, the project poses severe, hidden environmental and health risks.
