Many readers do enjoy reading what's unfamiliar to them. That's why genres like fantasy and science fiction are so popular - because the reader gets to experience something they wouldn't otherwise experience. With Amish romance, readers get to take a journey to a life they're unfamiliar with, without the constraints of modern technology to get in the way of human relationships.
Many years ago, Henry Yoder betrayed the Stoltzfus family and Leah Stolzfus, try as she might, has never forgiven him for it. Henry comes back into her life, claiming to be a changed person and vows to show Leah just how different he truly is. After Leah discovers a dark family secret, Leah relies on Henry to get her through it. Henry is determined to make amends and start over with her, but Leah isn't sure if she's ready yet. Even if she wants to be.
Amish romance is a literary subgenre of Christian fiction featuring Amish characters, but written and read mostly by evangelical Christian women. An industry term for Amish romance novels is "bonnet rippers" because most feature a woman in a bonnet on the cover, and "bonnet ripper" is a play on the term "bodice ripper" from classic romance novels.
