Never doubt in the darkness what God has shown you in the light.Amish Proverb Elsie Yoder can't forgive her sister, Katie, for leaving the community. Unable to let go of her sadness, she withdraws from her friends and family, nursing her feelings of betrayal. Gideon Lapp has held a special place in his heart for Elsie and longs to help her get through her troubles. Together they find comfort in their study of the "Martyr's Mirror," a centuries-old book that describes their ancestors' sacrifices for their faith through years of persecution. As Elsie opens up and begins to put her trust in Gideon, she tells him about the harassment she and her sister received at the hands of some local men. When the men return and threaten the community, Elsie and Gideon must stand together to do what is right. But can Elsie learn to give grace and to humble herself to accept grace as well?
