Female Zen teachers and writers

The Zen center where I live is very male dominated. This might be because it's very small. Anyway, I think Zen sometimes tend to be a bit masculine in its form, wit a kind of quasi militaristic approach. I find this kind of fun and try to have an ironic attitude - irony is indeed a good medicine. There are plenty of famous women in different schools of Buddhism, esecially Tibetan. But not so much in Zen, it seems. Is there anyone who knows a good book on Zen practice written by a woman? And I'd also like some online resources/courses/training on Zen by women.
