Both of Helen Boyd's books are good for those of us who are married or struggling with transition and relationships. (My Husband Betty, and She's Not the Man I Married).
Nevada was pretty decent too. Good fiction that isn't "erotic" - pretty much a first for quality transgender fiction that I know about.
Janet Mock's book, Redefining Realness - I can't say I enjoyed it, to be honest. I felt it focused far too much on the sex industry side of things, and if there's one thing trans people don't need, it's more people reading things that make them think we're all just a bunch of ex-hookers. But kudos to her for putting it out there and pushing trans issues front and center - she's still done far more than most to open doors for us all.
Warrior Princess - interesting story, just horrible writing. Painfully bad - clunky, middle-school level writing at best.
