Amish Honor — Samantha Price

At just seventeen, Honor Baker found herself an unlikely love -- her new brother-in-law. When the couple learns they won't be allowed to marry, their choice is obvious, and they do the only thing that makes sense.
When Honor goes missing, Florence finds herself in a car on a road trip with her mysterious English neighbor. Even though he has many qualities she admires, there are things about him that don't add up. Will they be able to find Honor and bring her home?
Which of Florence's younger half-sisters does something so wrong that she's sent to live with Aunt Dagmar?
