Meet Will and Becca Parsons, who've lived in Shelter Valley, Arizona, all their lives. Shelter Valley means everything to them. Home. Family. Security. Love. Everything that matters is right there in that town.

Will and Becca have been married for 20 years. It's a good marriage—a contented marriage—marred by only one disappointment: their inability to have children. But their dream of a baby has gradually been replaced by other interests, other goals.

In any case, Will and Becca are in their 40s now.

It's too late for babies.

Except it's not. Because Becca's pregnant. And that reality throws their carefully ordered lives into complete disarray.

A baby—after all these years.
