Remey Owens is desperate to move on with her life after the brutal murder of her next-door neighbour, Marlena. When the opportunity to housesit for her best friend's parents arises, it feels almost too good to be true. While staying in the beautiful Craftsman-style home, she hopes she won't hear the banging through the walls or Marlena crying, even if it is now only in her mind.

But things don't go as planned.

While she finds some solace knowing that Marlena's killer is dead, the calls from Remey's obsessive ex and the strange noises in the house make it hard to relax. And there's a prickling down her spine when she returns late one evening after a date-something's amiss.

Soon, it becomes apparent that she's not as alone as she believed. The quiet isolation of the home that had once seemed peaceful, now feels far more threatening. Here, there are no neighbours close enough to save her.

To survive the night, Remey must let go of everything she thought she knew about Marlena's death. Because the terrifying truth is more disturbing than she could have imagined, and it's coming for her too.
