Interference
(Book)

When her husband, a quantum physicist, goes missing in the midst of a strange, violent seizure, Brigid Bronik discovers that his research had gained unwanted attention and wonders if the very same physics that endangered him could actually be used to save his life.

Quantum physicist Matt Bronik is suffering from strange, violent seizures that medical science seems powerless to explain. He doesn't think these fits could be related to his research, which he has always described as benign and esoteric. That, it turns out, is not quite true: Matt has been prodding the mysteries of the quantum universe, with terrible repercussions for his health. And perhaps even for humanity as a whole. When Matt disappears, foul play is feared. His research had gained the attention of Chinese competitors, an unscrupulous billionaire, and the Department of Defense, among others. His wife, Brigid sets out to find him. Could the physics that endangered him actually be used to save his life? -- adapted from jacket
