Okay so i'm going to plug a series here that I love and hopefully you'll like it. It's the Emberverse series also known as Novels of the Change by S. M. Stirling. There's currently 11 books in the series and the first being "Dies the Fire". The first two books are slightly sci-fi in the setting as the whole premise is that all power has suddenly stopped working no engines, no batteries, no steam powered engines, and also oh yeah guns don't work either. But by the third book it takes a twist into Neo-Fantasy and magic actually becomes a big force in the world. There is a big power dynamic that evolves through the books with four or five main factions and more being introduced in almost every book.
You meet an LGBT character in the first book but it isn't until the third and fourth that another LGBT character becomes a big part of the story and she's a really well rounded character. Lots of tragedy and roller coaster moments in the series as a whole. There is some romance in the series and it plays a big role but more in the interactions of other characters and how that effects power dynamics. The only thing is the author does tend to have some redundancy in his writing but nothing that is over obvious at least to me.
I hope this was somewhat helpful and i'm sorry if it's just me rambling.
