When Secrets Kill

Samantha Devereaux's world is turned upside down from one phone call from her past- inviting her and Dan to their 10-year college reunion in Costa Rica. She didn't want to reunite with her old college friends-afraid of what she is harboring deep within her- - a secret too terrifying to tell her husband. She reluctantly gives in and agrees to go on this trip.
The body count rises, leaving one of the most beautiful places in the world into a burial ground. The killer is out there, watching her every move-a diabolical threat who knows way too much about everyone's past and killing them off one by one. Who is the killer? Does he know her secret? Is he connected to her past, or is this the work of a serial killer?
To answer these questions and protect herself, Sam begins looking into possible suspects and sees a killer in everyone around her. Sam doesn't count on the investigation led by the local police as she starts to look for the killer herself; at every corner lurks danger. Sam is determined to find the killer before she becomes his next victim and her secret is out.
