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.
Some[who?] argue that the non-Amish authors fail to understand Amish theology and how it differs in key areas from mainstream Christianity. They thus present characters who may appear Amish but who maintain an evangelical Christian worldview. For example, a character might proclaim an assurance of salvation, rather than a "living hope" of such as the Amish do. Amish specific beliefs such as non-violence, non participation in government, and an unwillingness to proselytize may be glossed over or not mentioned. Evangelical themes, such as sexual purity, are substituted.
While primarily written for and marketed to adult readers, some young adult Amish romance titles have been published as well. According to a September 2013 Library Journal survey, Amish fiction is the most commonly carried subgenre of Christian fiction in public libraries, although the survey did not distinguish between Amish romance and other Amish-themed literature.
