Adoring Addie, Courtships of Lancaster County by Leslie Gould by Bethany House Publishers.
When Addie Cramer's mutter and daed decide Phillip Eicher is the man for her to marry, they claim she must honor them by obeying their wishes. But then she falls in love with Jonathan Mosier - part of the family with whom the Cramers have a long-held grudge.
With the help of others in her community who long to see the quarrel healed, Jonathan and Addie struggle to continue their relationship against both sets of parents' wishes. But when one of Addie's vengeful brothers harms a member of the Mosier family, Jonathan intervenes and is banished from Lancaster County.
