A Miracle for Miriam by Kathleen Fuller
Very cute Amish Romance. Pretty short story.
Miriam fell for Seth, but he broke her heart. Years later, after he's nearly killed in an accident, Miriam sees him at a Christmas party and notices something is different about him-not just how he looks, but how he acts. When Seth pursues her, she must decide whether to guard her heart or accept his love.
