[EX Q]: I was expecting to read a book about the Amish. What I read instead was a very self centered book about a woman searching, rather blindly, I felt, for herself.She had very little in the way of insight into Amish life, even after spending a period of time with them. And her inability to get outside of her own head/her own life was not terribly interesting to read.For someone who always longed to be a 'star,' I am sure publishing a book was quite a thrill for her. Shame she used the Amish as a platform for her own ego.
[EX A]: Negative

[EX Q]: I ordered this and realized I didn't specify the size so went back 20 min. later to cancel the order and then order another one.the shipping is 3/4 the priced of the item! Then after what I thought was a canceled order didn't even work at all. I have been sending emails all day and tried to call them to no avail. Horrible communication. they took my money and haven't even responded to my email or phone call.Caveat Emptor
