The Amish Research Guide is a reference tool geared specifically for fiction writers who want to learn enough about the Amish to be able to create true-to-life Amish characters and communities. But it is also an interesting source of information to those who simply enjoy learning more about the Amish. It is available on Amazon in both eBook and print formats. For a limited time, the eBook version is only .99 USD (or free with a Kindle Unlimited membership).
