Ooh, I recognize Parrotfish, because I found it in my library's catalog when searching. I am glad to have been reminded.
The Well of Loneliness is not an FTM book, but rather about a lesbian (albeit a very masculine one). Nevertheless, it is quite good (one of my favorites) and I recommend it most highly. However, realize that invert is an olden word for homosexual, and does not mean introvert. I traversed through much of the book on that assumption, much to my future horror.
