When Lena Mercer wakes in the middle of the night and finds her husband missing from their bed, she follows him into the woods behind their home. Beneath an old cedar tree, she watches Owen bury a locked metal box-and hears him whisper an apology to whatever he has placed inside.

By morning, he denies ever leaving the house.

Then Lena receives an anonymous photograph proving she was not the only person watching him. The messages that follow point to Mara Vale, Owen's former fiancée, who vanished twelve years earlier just days before their wedding. As human remains are discovered near the Mercer property and long-buried evidence begins to surface, Lena realizes that nearly everyone connected to Mara has been hiding part of the truth.

Her husband is lying. His family is protecting something. And the person guiding Lena toward the answers may be the most dangerous of them all.

In a marriage built on secrets, Lena must uncover what happened the night Mara disappeared-before the truth claims another victim.
