I posted a whole list of Amish books on C.Ann's thread of 5-30-09 that if you search you can find it and there are many suggestions.
I have recently purchased 2 more authors, Amy Clipston--A Gift of Grace
Mary Ellis---A Widow's Hope, but I have not had a chance to read either one yet.
I love the Amish books--and to visit the Amish areas. We hope to visit the Ohio area around Walnut Creek, Sugar Creek in a few weeks, and hope to find a few more books that I haven't read.
Hope this information is helpful to somone who loves reading about the Amish.
