Co-authored by Sonya Sargent and Anthony M. Strong

When a woman returns to the scene of the horrific mass murder that shattered her life, the nightmare begins again in a chilling novel of psychological suspense.

Five years ago, Tessa Chamberlain was the lone survivor of a beach house massacre that left three of her friends dead—and Tessa with an inescapable, unending dread. Now she’s going back to face her fears.

Renting the same beach house where she almost died, Tessa returns to lonely Cassadaga Island off the coast of Maine long after the tourists and summer residents have departed for the winter. But as the fog rolls in and the nights grow longer, she wonders if she made a terrible mistake. There are footsteps on the porch, creaks from the second floor, and an unsettling feeling of being watched.

If only someone believed her. Because the terrors Tessa thought were long behind her are starting again. And this time, trapped and alone, she might not be lucky enough to survive them.
