I don't think 'Amish Affair' is a true story. Usually, such titles are fictional narratives designed to offer an interesting and engaging tale rather than being based on real events.
Most probably not. Amish communities have their own cultural and religious beliefs, and tales like this might just be fictional creations or misunderstandings.
Amish Grace is inspired by true incidents, but some artistic liberties might have been taken for the sake of the narrative. However, the core elements are rooted in reality.
It's difficult to say for certain. It might draw inspiration from real-life experiences, but it could have elements of imagination added to make it more engaging. You'd have to do some research or check the author's notes to know for sure.
