Sarah Collins needs an escape. Mourning her brother's death and the impending breakup of her marriage, she returns to her childhood home in South Carolina, where her family operated an inn.

Sarah hasn't been back to Sea Scope for twenty years; not since she and her brother Glen discovered a body by the nearby lighthouse. She never understood why her parents left Sea Scope so suddenly, or the reasons behind her father's suicide.

After Sarah returns to the inn, she faces long-buried memories, text messages and strange clues. Something is not right in Sea Scope. Reunited with people from her past, she tries to figure out what's going on in her childhood home.

When past and present collide, Sarah must face truths about her family, and what happened that summer day by the lighthouse. But will she survive to tell the tale?
