I have a friend of the online variety (not that this makes her any less a friend, it just means that we have never met F2F - yet).
Ruth Hull Chatlien has written a book about Betsy Bonaparte that I am most eager to read, having "watched" her work on it via Facebook for the last several months.
The book is titled The Ambitious Madame Bonaparte and it's scheduled to come out in December 2013. Ruth has a Facebook author page for it as well as a website.
I'm very excited about reading it, and about my friend's success. Huzzah!!
