The Traveler — John Katzenbach

From the New York Times�"bestselling author: “A powerful, obsessive novel of murder and madness” traveling cross-country (The New York Times).
 
Miami detective Mercedes Barren, recovering from a traumatic shooting, has transferred to the relative quiet of the forensics department to get her life back on track. Yet this peace is put on hold when she gets a wrenching phone call: Her niece, Susan, has become the latest victim of a fiendish serial killer. When a local man is apprehended, Mercedes is convinced he's guilty of all the murders -- except for Susan's. She has reason to believe her niece's killer is a copycat now heading across America, mapping out his next deadly moves.
 
To track him down, Mercedes enlists the help of his brother, Martin, a psychiatrist specializing in sex offenders. Now, they're following a trail of victims on a terrifying road trip where the lines between predator and prey begin to blur as they accelerate toward a “genuinely shattering climax . . . of devastating horror and suspense” (The Washington Times).
