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.
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.
