After leaving the mountains of her childhood, widow Molly Pierpont returns to help raise the children of her dead sister. She longs to enrich their lives, but how can a citified woman learn to make do in the wilds of Kentucky? Jonas McLean lost his heart when he lost his wife. Now, her sister, Molly, has come at his request - a request he didn't want to make. His daughter loathes the woman, while his son thinks she's his mama. And Jonas - well, he's not exactly sure how he feels about the spirited widow. Can grief extinguish their mustard-seed faith and crush their wounded hearts? Or will they allow their love for God - and each other - to move mountains of fear and pain?
