I'm a librarian who loves anime, manga, and reading a wide variety of genres.
Some authors I'd recommend:
Courtney Milan (m/f historical romance) - So far, I've only read her novella Unlocked, but I really liked it. (Unlocked is the only work mentioned in this list that I haven't reviewed.)
Jane Fletcher (f/f SFF romance) - Her Celaeno series has some serious flaws in its world-building, but I love it anyway. Rangers at Roadsend is a good place to start.
Tamara Allen (m/m historical romance) - I enjoyed her book The Only Gold.
Rose Lerner (m/f historical romance) - I enjoyed her book A Lily Among Thorns.
ETA - Whoops, one more! Here's another one I haven't reviewed, but that I remember enjoying: Sea Change by Darlene Marshall.
