Books for coming to terms with your gender identity

I've known I'm not cis for several years, and i vaguely label myself as nonbinary, but even that label isn't entirely accurate. i haven't actually done much to start presenting the way i want to present, as this has been a thing that i've mostly ignored for a long time. i just don't really want to deal with the reality that i'm unhappy with where i'm at right now, and i don't want to deal with the challenges of outwardly being trans. so if anyone has book recommendations, fiction or non-fiction, i would really appreciate it.
