Facing an empty nest for the first time since the death of her husband, Dan, three years ago, Tess Everett immerses herself in volunteer work for the Winterset public parks, home of the famous covered bridges of Madison County, Iowa. But when former resident J.W. McRae shows up at one of the bridges with paintbrushes and easel, sparks fly—because J.W. was once married to Tess’s late friend Char. Worse, J.W. was a deadbeat dad to Char’s son, Wynn—then a college student—who Tess and Dan took under their wings after his mom’s death.

J.W. hopes to make amends with his son now that there’s a new little granddaughter in the picture. But when Tess agrees to rent the backyard garage apartment to J.W., hoping to be a bridge to reconcile father and son, sparks of a different kind are kindled. As their friendship grows, Tess and J.W. must discover if what they have together is worth rearranging their entire lives for. And whether they can build bridges that will mend broken relationships.
