A big city detective. A lowcountry murder.

Peace, safety, a place to grieve and heal. After her husband is murdered by the Russian mob, Boston detective Callie Jean Morgan comes home to South Carolina. Her father hands her the keys to Chelsea Morning, the family beach house. There, she can keep their teenage son, Jeb, away from further threats. The sand, the waves, the ocean breezes ought to help them heal.

But the day they arrive at Edisto Beach, Callie finds her childhood mentor and elderly neighbor murdered. He was everything to her in her tender years. But she swore off law enforcement, and she tells herself she had to raise her son and stay away from the criminal element. It's what hurt her family to begin with.

However, taunted by the killer, who repeatedly violates her home and threatens others in the community, Callie finds her new sanctuary has become her old nightmare. Despite warnings from the town's police chief, Callie plunges back into detective work, pursuing a sinister stranger who may have ties to her past. He's turning a quiet paradise into a paranoid patch of sand where nobody's safe. She never thought she be back in the middle of a murder investigation, but she has no choice. Unfortunately, she'll do whatever it takes to stop him. She has no patience for murderers.
