The man she loves is gone. The house is empty. When missing-persons investigator Sarah Pribek starts looking for her husband, an FBI agent who has disappeared, what she learns shocks her. Who was he, really? Where is he? She knows the first 36 hours are critical. Her worst fear – that he may be dead – may be less painful than the truth. "Complex [and] shocking... [She] uses suspense as a powerful propellant."—Booklist
