Beneath the surface
(Book)

"After a harrowing experience with an obsessed patient, oncology nurse practitioner Leigh Weston needed a change. She thought she'd left her troubles behind when she moved home to Carrington, North Carolina, and took a job in the emergency department of the local hospital. But when someone tampers with her brakes, she fears the past has chased her into the present. She reaches out to her high school friend turned homicide investigator, Ryan Parker, for help. Ryan finds satisfaction in his career, but his favorite way to use his skills is as a volunteer underwater investigator with the Carrington County Sheriff's Office dive team. When the body of a wealthy businessman is discovered in Lake Porter, the investigation uncovers a possible serial killer--one with a terrifying connection to Leigh Weston and deadly implications for them all. Dive Team Investigations series."--Publisher's annotation.
