A recurrent, unidentifiable noise in her apartment. A memo to her boss that's replaced by obscene insults. Amanda-a successful architect in a happy marriage-finds her life going off kilter by degrees. She starts smoking again, and one night for no reason, without even the knowledge that she's doing it, she burns her husband with a cigarette. At night she dreams of a beautiful woman with pointed teeth on the shore of a blood-red sea.

The new voice in Amanda's head, the one that tells her to steal things and talk to strange men in bars, is strange and frightening, and Amanda struggles to wrest back control of her life. A book on demon possession suggests that the figure on the shore could be the demon Naamah, known to scholars of the Kabbalah as the second wife of Adam, who stole into his dreams and tricked him into fathering her child. Whatever the case, as the violence of her erratic behavior increases, Amanda knows that she must act to put her life right, or see it destroyed.
