Books on women religious (mainly in the Catholic tradition) who started religious orders or were known for their leadership ... check Paulist Press. One that comes to mine is Hildegard of Bingen...a composer, poet, artist and leader in her day. Paulist has a series of books, each focused on a particular person or movement in the history of Christian spirituality.

Also, Bill Judge has been doing ongoing research on women entrepreneurs and their spiritual paths, and presented a paper last year at the <st1:place><st1:placetype>Academy</st1:placetype> of <st1:placename>Management</st1:placename></st1:place> on his research. Bill's email is wjudge@odu.edu.

Karin Klenke is an author/scholar that comes to mind. While I don't have specific titles at my immediate disposal, I think her works might touch on your interest of feminine leadership and I would consider her a female spiritual leader.

This talk is not about her experience of female leadership, but rather how a female should lead :)
Also her book Meta Modern Era might be useful for you. I have not come across any talk by her in which she mentions that how was her experience of being a female leader but yes! there are quite a few talks about what is role of women in society and how a female should act/behave/lead in society.

There's an important feminist spirituality movement centred on the town of <st1:city><st1:place>Glastonbury</st1:place></st1:city>, usually known as the 'Goddess' movement. There's not a lot of academic writings about it, but the attached paper provides an introduction. The novel, 'Mists of Avalon' by Marion Zimmer Bradley, is also very important in the movement if you feel like reading some fiction!

An excellent place to start is The Crystal Chalice by Taj Inayat and The Unknown She by <st1:personname>Hilary</st1:personname> Hart.

You might look at faith and feminism: a holy alliance, Helen Kelly Hunt. Not academic; biographies.
