Hope deferred : an Amish romance
(Book)

Series information from Fantastic Fiction.

David Stolzfus and Anna Fisher have been best friends as long as they can remember. Sure, it was a bit unusual in the Amish community for a boy and a girl to be so close, but nobody questions it with David and Anna—it has just always been that way. Their lives are intertwined, the way the borders of their properties are joined by the Pequea Creek. When David, a bit older now and full of questions about faith, family, and the world, decides to travel to Australia, Anna is devastated to say goodbye to her best friend. But then she receives a letter from Leon Beiler, a young man she can't deny she has feelings for, and everything changes again. How can she reconcile a lifetime of close friendship with David with this new potential romance? And what will happen when David returns home?
