Kathryn Walker enjoys an enviable life. Her husband is an accomplished doctor, her children are bright and successful, and she devotes herself to charity work that uplifts her suburban Colorado community.

Already distraught over the child she miscarried in this same cursed month many years ago, the emotionally fragile woman isn’t ready to consider the overwhelming evidence that someone may be trying to take her husband --- and her life.
