God Loves Hair was a 2011 Lambda Award Finalist and self published. To buy a copy its best to go directly to the author's site.
A Map of Home by Jarrar is classified as fiction and works very well as a YA crossover.
I've been hearing great things about Torres debut We the Animals which is also classified as fiction. From the description it looks like it has some YA crossover appeal as well.
The LGBTQ characters in Pull and Jazz in Love are secondary, role players but their presence is felt.
