Be careful who you let in . . .

After her husband Nick’s tragic death, Ally is barely keeping it together. The once–glamorous architect drowned just steps from their quiet riverfront home and now Ally spends her sleepless nights haunted by grief, guilt, and questions she can’t answer.

Her teenage daughter Paige is slipping away, and the house that once held their happy family now feels like a tomb—until Marcy shows up.

Marcy: the childhood best friend Ally hasn’t seen in over a decade. The one who needs “a place to stay . . . just for a few days.” At first, she’s helpful. Warm. Familiar. But then Ally starts to forget things—where she left her keys and whether she took her pills. Paige doesn’t trust Marcy. Ally isn’t sure she trusts herself.

As the past resurfaces in fragments, Ally starts to wonder what really happened the night Nick died—and how well she ever knew the friend now sleeping just down the hall.

Because someone is lying. And in this house, the truth is a killer . . .

A compulsively readable thriller perfect for fans of Freida McFadden, Lisa Jewell, and Alice Feeney.
