“A story of murder and revenge . . . Outstandingly well paced and tightly plotted, the novel also stands out in its handling of various psychological themes.”—Booklist

Eerily attuned to one another, twins Regina and Renata are so identical that even their mother can’t tell them apart. Then tragedy strikes: a vicious attack leaves one twin dead and the other so traumatized that she turns totally inward, incapable of telling anyone what happened or even who she is. She remains lost to the world, until the day Mark, a family friend, comes to visit—and the young woman utters her first intelligible word.

As she recovers, still with no memory of the past, her nightmares grow steadily more frightful, followed by wild fits of hysteria and dark mood swings. Her strange outbursts seem to coincide with the grisly serial murders that have begun plaguing Seattle. Could she be the killer? Determined to dispel his suspicion, Mark stakes out her home. The unholy sight he witnesses one night will haunt his soul for the rest of his life. . . .
