Author Grady Green is having the worst best day of his life.

Grady calls his wife as she's driving home to share some exciting news. He hears Abby slam on the brakes, get out of the car, then nothing. When he eventually finds her car by a cliff edge, the headlights are on, the driver door is open, her phone is still there .

. . but his wife has disappeared.

A year later, Grady is still overcome with grief and desperate to know what happened to Abby.

He can't sleep, and he can't write, so he travels to a tiny Scottish island to try to get his life back on track. Then he sees the impossible: a woman who looks exactly like his missing wife.

Wives think their husbands will change, but they don't.
