The secrets it exposes threaten to change their lives forever.

Molly and Liza have always been enviably close. Even after Molly married Daniel, the couple considered Liza an honorary family member. But after Liza moved away, things grew more strained than anyone wanted to admit-in the friendship and the marriage.

When Daniel goes away on business, Molly and Liza plan to reconnect with a nice long video chat after the kids are in bed. But then Molly leaves the room to check on a crying child.

What Liza sees next will change everything.

Only one thing is certain: Molly needs her. Liza drives all night to be at Molly's side-but when she arrives, the reception is icy, leaving Liza baffled and hurt. She knows there's no denying what she saw.

Or is there?

In disbelief that their friendship could really be over, Liza is unaware she's about to have a near miss of her own.

And Molly, refusing to deal with what's happened, won't turn to Daniel, either.

But none of them can go on pretending. Not after this.

One moment will change things for them all.
