Desperate and alone, she discovers his disappearance is linked to a woman from his past, someone he swore meant nothing. But as Olivia digs deeper into the lies unraveling her marriage, she uncovers a connection between this mystery woman and her own forgotten childhood, a truth buried so deep she's spent her entire adult life running from it. Now someone is watching her every move, leaving cryptic messages that suggest they know exactly what she's trying to remember. And they'll do anything to make sure some secrets stay buried—even if it means destroying what's left of her family.
