Lee Stein's demons are catching up with her and her road-worn marathon sneakers... Horrifying nightmares force Lee to constantly relive the bloody act of negligence that took her brother's life in childhood, and her philandering husband has been tormenting her with a steady stream of mistresses right under her nose. With her marriage in shambles and harboring a shameful secret she dare not tell anyone, she's drowning in a miserable pool of empty nest syndrome. Then Lee begins to feel the quiet tug of a sinister malevolence threatening to rupture from the dark place we all have inside. A chance encounter with an attractive barista turns Lee's world upside down, and when she finds herself falling for Abby, a captivating young mother, she feels she may have a shot at redemption after all. But happiness can come at a heavy price, and Abby's own bloodthirsty past threatens to destroy their happiness with a true predator's brutality. Can Lee harness the monster within to save Abby from a deadly fate and find peace with an ancient guilt? Or will she run back to a murky facade of the perfect life?
