Book Recommendations

Hello! I am asking for book recommendations for my trans boyfriend. So he isn’t out yet and we have been together for a long time(almost 6 years!!) but we are getting to an age where we both are in college now and he isn’t out and the longer he goes without coming out the more anxious and anxious he gets. I feel like from talking with him he’s also just struggling with his transness just since he’s not out he doesn’t really have that in person community and of course he talks to people online but he doesn’t make those real life connections with other trans men in a open way. We are of course looking into therapy and everything but I really would like to get him some books cause he loves to read. Just books that shine more on the trans experience and navigating this part of his life. I was trying to research them and find out what’s worth buying but it’s all so over my head because I don’t the perspective you guys will have. Sorry if I rambled a little I have so much to say but I was trying to just get to the point haha. Thank you guys!
