My all-time favourite is "The Queen of the Grove" by Louise Malatesta. I never had Femdom things in real life, but - unlike so much else - this book is beautifully written, and basically the dominant person in the stories could have the other gender just as well.

The other one I like a lot is "The Q Letters" by SirQ, which provides good insight into a Dom´s world of feelings, especially at the beginning of his experiences.

I also like the books of Sina-Aline Geißler, but she´s German and I do not know if her books were translated into other tongues; my favourite one by her is "Mut zur Demut".
