Newly married and with a baby on the way, Jacy has everything she ever wanted. When she and her husband, Jed, go to visit his father in his remote cottage, Jacy feels bathed in love by Dr. Ash, if less so by his housekeeper, the enigmatic Mrs. Brandt.

Then Jacy has a health scare. Swiftly, all eyes are on Jacy's condition, and whispers about Jed's long-dead mother seem to be intruding upon the present. As the days pass, Jacy feels trapped in the cottage, her body under the looking glass. But are her fears founded or is this -as is suggested to her-a stubborn refusal to take necessary precautions to protect her unborn child? The dense woods surrounding the cottage are full of dangers, but are the greater ones inside?
