Women of the Golden Dawn

One of the best books on the Golden Dawn and essential for those who want to understand its history. The men are in the book, too, but it gives important exposure to the pioneering and influential women in the world's most influential occult order.

Other reviewers have griped about the inclusion of astrological content, but the members of the order took astrology very seriously, so it absolutely makes sense to include it (and if you don't care for astrology just skip those bits).
