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 into the depths of fear with an exciting new voice in romantic suspense. Award-winning author Lynn H. Blackburn grabs readers by the throat and doesn't let go until the final heart-pounding page.

Adam turns to his friend Dr. Sabrina Fleming—a professor at the local university with unparalleled computer security and forensics skills—to recover the files from the laptop. But the deeper they dig, the deadlier the investigation becomes. When evidence uncovers a human trafficking ring and implicates members of Adam's own family, he and Sabrina will have to risk everything to solve the case. The truth could set hundreds free—but someone is willing to do whatever it takes to silence anyone who threatens to reveal their secrets. Award-winning author Lynn H. Blackburn invites readers back to Carrington, North Carolina, where everything is not as it seems and sinister elements lurk behind the idyllic façad
