I really like reading fantasy books, like things by Terry Brooks and Trudi Canavan. Just recently bought The Written by Ben Galley - loving it so far. Just wondering if there are any fantasy books with gay characters?
Harry Potter - Albus Dumbledore is gay. Just had to throw it out there, haha - I don't know of any less main-stream fantasy books with gay characters.
"The Rain Wild Chronicles" by Robin Hobb have a gay couple. Not sure about a lesbian, but one gay couple is better than none! I really like the books aswell. Good fantasy, about dragon, which contain class-issues, love over boundries, intrigues and fighting. Also, there are lizard/nature people. It's Awesome!
Wiki has nice lists about LGBT characters in any given artistic section List of LGBT themed speculative fiction and List of LGBT characters in Modern written fiction Hope those helps.
I started a book called the huntress (has a brunette on the cover holding a sword and it's purple). It's a lesbian novel and she lives in a school sort of thing and there's fairies. That's all I know so far but it seems good.
The Last Herald Mage trilogy by Mercedes Lackey: Magic's Pawn, Magic's Promise, Magic's Price. The lead characters are basically a gay male couple.
I was about the suggest Mercedes Lackey! She has quite a few gay characters in her books. Her Valdemar books are awesome.
