trans-spirituality:

Gender and Transgender in Modern Paganism
First Edition, January 2012
Free Ebook by Cerridwen Press
(Printed copy available as well.)

From the preface:

The voices you will read here are from both cisgendered and transgendered, male and female, queer and straight, old and young. We present these essays as they were sent to us, with no commentary. We give these words to the community as a way to build understanding and to give people the opportunity to decide for themselves how to act.

It is our will to create change, but how that will happen will not be decided by a select few, but by our community as a whole. As paganism comes more and more into its own, we need to learn how to work and live together with understanding and respect. If we do not learn from the mistakes of other religions and put our own house in order, we will not survive.
