The second part of my "Site That Sell M/M Fiction" post.
BLIND EYE BOOKS
An independent press dedicated to publishing science-fiction and fantasy stories with gay and lesbian protagonists. I love this press! Here you'll find books length 70,000 to 150,000 (300-600 pages), which, in true fantasy style, are longer than romance novels.
SILVER STREAM PRESS
A publisher of various genres with LGBT, straight, and menage stories available.
LGBTQ publisher. Gay, lesbian, and trans romance and erotica available.
A publisher of m/m fiction that deals primarily with stories set in either the present, the past, or alternate universe versions of the present or past. (On an amusing note, their "About Us" page thanks someone for their "immoral support".)
LESS THAN THREE PRESS
Another popular one! They publish m/m, f/f, trans, and polyamory romantic fiction. They also have a "serial fiction" thing going on that's pretty cool, as well as traditional books and ebooks.
A publisher of romantica and erotica. They publish straight, gay, and lesbian fiction.
A publisher with only a handful of titles available. Not romance, but instead, thrillers and such. Some of their titles are m/m, I believe? Just check it out, I guess.
PINK PETAL BOOKS
A romance publisher with gay, lesbian, and bisexual romance available. (They say they have "GBLT" romance, but I haven't seen any trans titles.)
A general publisher of GBLTQ fiction and non-fiction. Romance, erotica, guides, anthologies, gender studies, and human rights fiction available.
