Hypatia: The Life and Legend of an Ancient Philosopher - Edward J. Watts
As the title says. The author tries to stress the fact that the book is primarily about her life and work, which always gets overshadowed by her death. It was pretty good as both a book about her, and general Alexandrian life in her age, but quite short (around 150 pages)
Women Writers of Ancient Greece and Rome: An Anthology - Ian Michael Plant
Contains fragments from ancient women writers about various topics. It was good, but sadly not much was preserved through time, the fragments were often very short.
