Matthews, Susan R.    Lesbian Author!

Category: Far future
Summary: Andrej Koscuisko is a doctor whose social position has forced him into the job of Ship's Surgeon, which means part of his job is torturing political prisoners. Though he is a moral man, he discovers he really enjoys that aspect of his work. Lots of (male) homoerotic tension. The other two books in the series are not nearly as good.

Summary: Part 1 of The Saga of Pliocene Exile. A one-way time tunnel opens to Earth of six million B.C. and all the folks who felt they didn't fit into the Galactic Milieu went through it. Unfortunately, they discovered that someone else had gotten there first.... Has one lesbian, a 19 year old who is rather obnoxious, but by the fourth book redeems herself. Julian May's Galactic Milieu novels usually have gay characters.

McArthur, Maxine    

Category: Space-based
Summary: Maria Halley commands the space station Jocasta. The station is under seige by an alien race no one can communicate with. The residents and refugees are hungry and tired of the blockade. The computer system keeps failing in mysterious ways. And the alien ambassadors of the Four Worlds are being anything but helpful. The last thing she needs is evidence that a tireless, viciously imaginative killer is on board the station.

McHugh, Maureen F.    

Category: Science fiction
Summary: Woman passing as man. Transgender stuff.

McMahon, Donna    

Category: Dystopian future
Summary: Runaway Klale Renhardt learns to survive in the troubled Vancouver of the 22nd century. The Klon-dyke bar becomes her haven. Very solid characterization and plot building. Most of the sexuality stuff is “bent” in the book's terminology.

Mitchell, Lorna    

Category: Science Fiction
Summary: It was a little too heavy on the 70's feminism by the end, but I enjoyed it overall. The revolution referred to in the book is Jone's discovery she's a dyke.

Mitchison, Naomi    

Category: Dystopian future
Summary: Solution Three presents a future society in which reproductive control and homosexuality shape a more equitable life for all, eradicating aggression and racism, curbing overpopulation, and providing a dependable food supply. But there are those who are rebelling in this peaceful world.

Mitchison, Naomi

Summary: So out of print it isn't even on Amazon.

Summary: Out of print. I don't even remember what it was about.

Mixon, Laura J.    

Category: Science Fiction
Summary: Manda is a clone like everyone else in her colony, but her twin clone died in vitro, so she is also, paradoxically, a singleton--and a loner. Her discovery of alien life brings both discord to the colony and a healing to her relationship to it. One of Manda's clones was in love with another woman.

Mixon, Laura J.

Summary: Carli D'Auber and her team of scientists are fine-tuning their invention of proxies--artificial bodies that people can upload into. Sometimes they wear proxies of a different gender and go out to get laid.

Summary: Ruby and Golem, her android, attempt to save a rich Egyptian from a collapsing skyscraper, but end up with more trouble than they bargained for. Ruby is a lesbian.

Morehouse, Lyda    Lesbian Author!

Category: Science Fiction
Summary: In some ways my favorite of the books in this series. The writing is really good. The one thing that makes me give these a lower rating than perhaps others would is the religious mythology informing the books. It’s just not an interest of mine. I’d love to see Morehouse do some “straight” sci fi.

Morehouse, Lyda    Lesbian Author!

Summary: Sequel to Fallen Host. One of the main characters is a lesbian.

Summary: Deidre McMannus has had her connection to the LINK, a worldwide virtual-reality interface, severed as punishment for a crime she did not commit. She finds that she is uniquely qualified to determine the truth of the rumors of “angels” in the LINK. The leader of the rebels is a lesbian.

Morgan, Richard    

Category: Cyber-punk
Summary: Two minor female characters, Jadwiga and Kiyoka, are lovers. The book is the third in a series about Takeshi Kovacs, former Envoy for the Protectorate, now living a life of petty crime. The first two books give some background to this one. They are Altered Carbon and Broken Angels (both 4 stars, but no lesbians). This edition of the book is only available in the UK, so if you are interested, go to amazon.co.uk to check it out. He has another book out, better than the Kovacs novels in my opinion, called Market Forces.

Moriarty, Chris    

Category: Science fiction
Summary: In four hundred years, how will humans, post-humans, clones, and AIs coexist? This book explores those issues and throws in a bit of spy thriller and myrmecology and terraforming and complexity theory and more. Very dense, character-driven hard science fiction. Catherine Li, the star of Spin State, is a major character in this novel as well, though not the main character.

Moriarty, Chris    

Category: Tough Women
Summary: I heard about Spin State from the author, who told me the main character was a lesbian, “though in the spirit of truth in advertising, the main character lives in a future with much more fluid attitudes about gender and sexuality and is probably more accurately described as ‘equal opportunity with a strong preference for girls’.

Moroz, Anne    Lesbian Author?

Category: Space opera
Summary: The story is reminiscent of the Alien films. Deep space exploration crew encounters alien life form that takes over. Hero escapes in a lifeboat. Months later, she is rescued. The company she works for sends her back to bring home some of the life forms. The author is listed as a lesbian on the feministsf.org web site.

Morse, David    

Category: Time travel
Summary: Maggie Foster is sent back to 1773 England from a future in ecological collapse to spoil the success of the world's first iron bridge, on the theory that this will slow or halt the industrial revolution. Includes a lesbian romance.

Ore, Rebecca    

Category: Time travel
Summary: Not your typical time travel story. Earth in the 24th century has received time machines from its own future. The "Archives" use them to grab people from the past. Most of them go crazy or die, until they bring up the Italian woman Benedetta. The book is somewhat unusual in that it never reveals what is going on behind the scenes--you're left just as uncertain as the characters themselves. For me, the biggest flaw was that Benedetta didn't get enough airtime. The two male protagonists got more than their 66% worth, and since both of them started out as unlikable, it made me even more frustrated that I didn't get more of Benedetta's side of things. Ore has another book in this collection, but my favorite of her's is Gaia's Toys, which is in the Other Books section.
