When Eugene Mast leaves his Amish community in Worthington,
Indiana, to teach in faraway Kalona, Iowa, he also must leave the love
of his life, Naomi Miller.

For the next nine months of the
school term, Eugene and Naomi keep their romance alive through love
letters from his heart to hers, and from hers back to his.
writes of his concern that in his absence Naomi may find the
attractions of another suitor to her liking. Naomi worries that Eugene
may fall prey to the liberal Mennonite beliefs in the community where
he now lives. Both can hardly wait until the school year is up and
they’re finally reunited.
