"Book of ages: the life and opinions of Jane Franklin", by Jill Lepore. There is a wealth of riches still to be mined from historical documents that reveal the lives of women. It's incredible to know how much is lost to history because half the population has been left out of the accessible record (i.e. books). The author was a voracious reader and as she read volume after volume of Ben Franklin's writings she found letter after letter written to Jane Mecom. There were no records of return correspondence since the volumes were about Ben's writing. Lepore tracked what letter's of Jane's that remained down. What an incredible story Lepore documented. You can see CSPAN Book TV online and can look up this author's talk and hear it directly. It was fantastic, she's a great speaker and judging from her discussion of the book, a great author. I've put a hold on the book from the library so I've not read it yet. I'm number 125 holds of about 8 copies or something but that's OK because I have a lot backed up right now and the timing will be about right when the book comes up, or, I'll end up buying a copy if the timing's not right.
