I've got my foot in both camps.
I've been active on this board for a while, and I write some of the content.
Recently I
posted that I'd like to interview people who have been financially exploited by friends or family. The aim of the book is to show that these types of events are extremely common, and to help prevent people from making similar mistakes. Several agents are reviewing the proposal.
Thanks to the people who have already responded to me off-line. They are, of course, welcome to post about their experiences here if they choose.
