In the five years since the fateful and horrific night that changed her life, Sandra Leigh has kept herself sequestered at the Compound, a trauma recovery/survival skill camp that helped her process her past and feel safe in the world again. Now, the time has come for her to face life outside the Compound, and that starts with a family road trip to rebuild the relationship she once had with her young niece.
 
A weekend at a rented cabin in the woods sounds idyllic, but Sandra begins to notice that things are off. Strange sounds and shadows, combined with a less-than-welcoming atmosphere at the nearby small town, put Sandra quickly on edge. Is it all just her paranoia coming into play, or is there something truly dangerous happening?
 
When her niece discovers a cryptic message hidden in the cabin's guest book--THEY CAME AT NIGHT--Sandra realizes that her family is caught in the crosshairs of a heinously sinister plot, and she will need to call on all the skills she learned at the Compound to save them... if she can.
