Betsie and Samuel married for love, but only three years down the line, their relationship has been forced to take a backseat to children, and other responsibilities. Their marriage is already strained when Melvin, Samuel's father, comes to stay with them. He's a crotchety old man who brings misery wherever he goes. Matters come to a breaking point when their first child is kidnapped without a trace. Will Betsie and Samuel's marriage survive this turmoil? Will they ever get their daughter back? And will Samuel finally find it in his heart to forgive his father? The Heart of Forgiveness is the fourth and final book in the Amish Hearts series (the prequel to the Amish Sisters series). Each book is a stand-alone read, but to make the most of the series you should consider reading them in order.
