"Justin Westwood, once a big-city homicide detective, has moved to the small Long Island town of East End Harbor to escape his haunting past, but his instincts kick in when a reporter dies in what he suspects was not an accident, and he soon finds himself in the middle of a complicated murder case involving a weird quest for the fountain of youth."@en
"The murder of a young female journalist draws Justin Westwood, a small-town Long Island cop, into a dangerous investigation that forces him to confront his fellow cops, the FBI, and an oddball team of professional killers."
"It looked for all the world like a terrible, tragic accident. Susanna Morgan had gotten up in the middle of the night, tripped, fallen, and broken her neck. Yet when detective Justin Westwood inspects the victim's apartment, he can't help noticing that the details don't quite add up. The glass on the bedside table is knocked over but there are no cuts on her body. The scrape on her knee looks suspiciously fresh. And then a terrified witness comes forward, confirming his worst fear."@en
