This is an entirely idiosyncratic selection of more or less LGBT-themed books that I've reviewed so far. Please note, the attribution of stars is based on the Michelin guide system. So:
No star doesn't mean it's awful, but it's definitely missable. Read the review.
1 star: Definitely worth your time.
2 stars: An important work.
3 stars: A classic.
