Twins Rachel and Rebecca Mast keep few secrets from each other, but even Rebecca doesn't know how great the ache Rachel holds in her heart ever since Rebecca started dating the charming John Yoder. When will it be Rachel's turn for love? Despite having a willing suitor in the vainglorious Wendell Kaufman, a man who once unsuccessfully pursued her sister, Rachel's attention is fixed on Milton Beiler. Milton hasn't paid Rachel the least bit of attention, and worse still, he's on rumspringa and conflicted about permanently joining the church. Meanwhile, Rebecca's world is turned upside-down when a tragic accident threatens her dreams of becoming John's frau. Despite the obstacles in her path, Rebecca remains steadfast in her faith. Will Rachel's love for Milton win out over his love for the world, and is Rebecca strong enough to face an uncertain future with John? Only the Lord has the answers the Mast sisters so desperately search for.
