In case you're looking around for some YA transgender books, the Friends have a little help to offer. Here's a list of 10 books to check out by trans authors. Maybe the folks over at GayYA can give you more book ideas.
But as the Guardian itself points out: "Please keep in mind that many of these books are published through small presses, so they likely won't be available in physical bookshops." The Friends would like you to know that at least HALF of them are available in the Western MA library system, though.
