I can't blame this book for not giving me the information I was hoping for. *Nobody* seems to know for sure how women in Regency England dealt with the flow.
But "Flow" was an engaging enough book to hold me until the end, anyway. The period (in every sense) product ads alone are worth the price of the book, though I'm not sure I wanted to know that until fairly recently, women were encouraged to use bleach-based products to stay "fresh." (Lysol douching, kids. It happened. I'm scared.)
