The coauthor of Beowulf's Children strikes out on his own with this novel of mystic revelation and martial arts. What if the disciplines we know as the martial arts, meditation, and fasting were mere fragments of a greater, more powerful killing art? What if that hidden discipline could produce in a man the power to manipulate matter and energy at will? What if the effect on the mind were so deadly that, uncontrolled, the result would be an inhuman killer? And what if, unknowingly, a young man in modern-day Los Angeles were to stumble onto the secret, setting in motion The Kundalini Equation?
