>>131155I haven't read it personally, but I've heard Playing Big by Tara Mohr is a good book on overcoming imposter syndrome for women. For biographies:
- Empress Dowager Cixi by Jung Chang
- The Secret History of the Mongol Queens by Jack Weatherford (by a man, but he uncovered a lot of important and formerly unknown history about female Mongol rulers and made it available to the west)
- Ruth Bader Ginsburg: A Life by Jane Sherron De Hart
- Stories of the Sahara by Sanmao
- Charlotte Brontë: A Fiery Heart by Claire Harman
I also think the site Rejected Princesses is a great place to identify prominent historical women so you can do further reading.
