Seth Webster's heart never healed after he lost his adored wife. Now, with Christmas approaching, wild twin boys to raise alone, a home in chaos, and the latest in a long line of exasperated housekeepers quitting in disgust, Seth needs more than help to keep his family together...he needs a miracle.

And then one arrives on his doorstep. Her name is Mrs. Merkle, but the kids call her "Mrs. Miracle"--and from the moment the warm, knowing, and very patient nanny appears, everything is different. Her sassy spirit is infectious, and it gives Seth the courage to approach Reba, a beautiful travel agent who's been hurt and betrayed, and is afraid to ever love again.

Through the magic of faith--and with a little help from a children's Christmas pageant and a lot of encouragement from Mrs. Miracle--Seth and Reba might just be able to find a Christmas miracle of their very own: true love.
