The book that introduces FBI special agent Tess McCallum.
"To any thriller fan who didn't sleep through the 1990s, the protagonists of Prescott's fifth novel (following Last Breath) will seem comfortingly familiar: the heroine is a blonde, gray-eyed single (and single-minded) FBI agent; the villain is a crafty, complex and completely insane serial killer. Unlike cannibal Hannibal, however, the mysterious Mobius is not a unique monster; he's terrifying precisely because he's so ordinary, an everyman who could be just about anyone ... or anywhere. And unlike cool Clarisse, Tess McCallum's career and psyche have both been frozen since the night she arrived at her "secure" home to find her fellow FBI agent, and supposedly secret lover, ritually murdered by the slippery sex-killer she had been pursuing. Now, two deceptively quiet years later, Mobius is back, with a new identity and a new weapon that enables him to morph from mere serial killer to mass murderer—unless Tess can find the elusive madman before he kills her, along with much of Los Angeles. Unrelentingly suspenseful, this psychological chiller is only for those with a high terror threshold.”—Publishers Weekly
