I've just read "The art of being normal" by Lisa Williamson,a young adult ( hey I can dream) book about a boy wanting to be a girl and a girl transitioning to a boy. Very good and even brought a tear to my cynical eye... "The new woman" by Charity Norman is a transgender tale of a middle aged TG who finally realises he needs to live his life as a woman. I've also just read " Fanny & Stella. The Young Men Who Shocked Victorian England". This is a true story of two crossdressers/TG's who were arrested in 1870 and scandalised Victorian England. There's a lot of conjecture and supposition but it's an enjoyable read and window into Victorian society.
On a personal note I'm not a fan of "fictionmania" due to the age of some of the characters.
