Echoes

From Library Journal:

"Like the best of Dean Koontz's supernatural chillers, this novel forces readers to suspend disbelief – in this case, to the point of accepting the premise that demons are taking over the world. Strange, literally earthshaking events are taking place: the kidnapping and murder of several world leaders, earthquakes in France, fissures in the earth. In San Paradiso, California, several powerful people suddenly have look-alikes behaving oddly, even murderously. Political reporter Laura Bennett must fight the demons within herself to retrieve from her memory the explanation for this otherworldly invasion. Former AP editor and veteran novelist Hyman (The Eyes of a Stranger, St. Martin's, 1987) has written a compelling tale, recommended for horror collections."
