This list has the best LGBTQ fiction and nonfiction I've read so far (these all got four or five stars on good reads). A lot of the fiction is teen lit, I know. The fiction is either by an LGBTQ author and/or about LGBTQ characters and issues.
There are a few manga titles that have LGBTQ themes as well (most are m/m or f/f romances).
I've read all of these titles between 2010 and February 2019.
The nonfiction is all about or by people who identify as being either gay, lesbian, bisexual, transgender or queer.
EDIT: I wouldn't have put The Happy Prince on this list if I waited until I finished it. I only gave it three stars but because you can't edit these lists, it stays.
