When Elena Reyes accepts a live-in caretaker position at the remote Winter Estate, it feels like the second chance she's been begging for. Her only responsibility: care for Dr. Adrian Winter, a once-renowned neuroscientist recovering from a mysterious illness, and follow three rules set by his elegant yet unnervingly cold wife, Lucille: Never leave Adrian alone.Never let him handle his own medication.And most importantly never open the basement door.But when Elena begins hearing muffled cries and whispers rising from the depths of the house at night, she starts to fear that Adrian isn't the only one trapped behind Winter Estate's locked doors. And the closer she gets to the truth, the clearer it becomes: Some secrets aren't meant to be cared for... they're meant to be buried.
