Book cover of The Librarian and the Orc: A Monster Fantasy Romance (Orc Sworn)

E.J. Frost Author Of Snowburn

From my list on scifi and fantasy romance.

Why am I passionate about this?

I’ve been fascinated by “other worlds” since I found my father’s battered copy of Dune when I was eleven. I’ve been seeking that experience of transportation, of transcendence, that I got from reading Dune, ever since. I’ve found it in diverse places, from the very alien worlds of Jo Clayton’s Diadem from the Stars series to the somehow-familiar woods of Richard and Wendy Pini’s ElfQuest comics. I’ve tried to give that experience back to my readers, in creating worlds wondrous and strange but entirely relatable. The books on this list sparked that same sense of transcendence and I hope you enjoy them as much as I did!

E.J.'s book list on scifi and fantasy romance

E.J. Frost Why did E.J. love this book?

Fenn’s Orc Sworn series transports the reader to a world both familiar and utterly strange, where gray-skinned, monstrous orcs show courage, kindness, and compassion to the human women they desperately need to continue their race while being hunted by human men. It’s a world of darkness, oppression, and fear, but also wonder, beauty, and hope. Fenn’s world building is utterly immersive—you will hear, feel, smell (and only rarely see, because it’s dark under Orc Mountain!)—what it is to be Orc Sworn.

What is this book about?

He’s a fierce, ferocious, death-dealing beast. And he’s reading a book in her library...

In a world of recently warring orcs and men, Rosa Rolfe leads a quiet, scholarly life as an impoverished librarian — until the day she finds an orc. In her library. Reading a book.

He’s rude, aggressive, and deeply terrifying, with his huge muscled form, sharp black claws, and cold, dismissive commands. But he doesn’t seem truly dangerous… at least, until night falls. And he makes Rosa a shocking, scandalous offer…

Her books, for her surrender.
Her ecstasy.
Her enlightenment…

Rosa’s no fool, and she knows…

E.J.'s book list on scifi and fantasy romance

E.J. Frost Why did E.J. love this book?

This book made me completely shift my frame of reference. Why? It’s set in the modern world. It should be familiar to me as a reader. But it’s not. It’s wholly “other.” It’s a world in which moth fae and succubae use a dating app to set up their monstrous rendezvous. It’s a world in which they work side by side with humans, one of them “out” and public in every way, the other closeted and fearful, and it’s not the ones you might expect. It’s a world of deep needs almost too ugly to be expressed which drive behavior in a way I immediately recognized, and sympathized with, but only when seen through the lens of these very alien characters in a very familiar world. It’s a world that requires you to completely open your mind, and you will come away much richer for it.

E.J.'s book list on scifi and fantasy romance

E.J. Frost Why did E.J. love this book?

“What if?” That’s the question sci-fi and fantasy authors have been asking for over a hundred years. What if humanity was dying and aliens offered salvation, but only at a terrible price? That’s the question this book poses, and it does it so compellingly. The story’s set on a poisoned world, and in a dying race’s spaceship. There is no escape here except death. There are no familiar, comfortable spaces. Nowhere left to hide. There is only the smallest spark of hope: that the humans can somehow connect with the aliens who are “not squid” but absolutely not like us. To do so, they have to overcome the basest squeamishness of human nature, and that they do makes for not just brave characters, but an extremely brave book.

What is this book about?

“It will take the whole night at least,” he said, “to implant all my eggs.”The colony planet is a death trap. Only the tiniest fraction of humanity survives the gruesome rejection virus.

And then the aliens arrive.

The Nepenthe, too, seek a new home world, but discover instead a species capable of incubating their precious eggs: humans.

The two dying races can either reach an agreement to help each other live on … or prepare for extinction.

Publisher's Note: The We Are Nepenthe series contains tentacles, shapeshifting aliens and squirm-in-your-seat depravity. A one-click read for the seriously adventurous only.


Book cover of The Last Hour of Gann

Melody Johnson Author Of Beyond the Next Star

From my list on sci-fi that will melt your heart.

Why am I passionate about this?

Science fiction is a wonderful genre and a fun one to write because it offers authors the opportunity to explore age-old topics from a fresh perspective. For me, as both a writer and a voracious reader, the one thing that ties me to a great story—no matter the genre—is romance. Whether the hero is an alien from a faraway world or a werewolf with mechanical organs, the heart of a story is its characters, the relationships they form, and the healing power of love. Below are my top five recommended reads in science fiction that are sure to melt your heart!

Melody's book list on sci-fi that will melt your heart

Melody Johnson Why did Melody love this book?

All of R. Lee Smith’s novels are dark, explicit, and fascinating, but my favorite (and it was a Sophie’s Choice, for sure!) is The Last Hour of Gann. The heroine, Amber, and her spaceship full of fellow pioneers crash land on a dystopian alien world inhabited by lizard people. The humans are woefully unprepared to survive in the wild and all too willing to turn on one another. When a passing lizard/warrior/judge, Meoraq, stumbles upon their camp, Amber jumps at the opportunity to beg for his aid, a near-impossible task without knowing his language. Together, they learn to communicate, and as Meoraq embarks on the futile task of keeping “his humans” safe, so begins the delicious, inexplicable, slow-burn romance between woman and lizard that I never knew I needed.

For the survivors, there is no rescue, no way home and no hope until they are found by Meoraq—a holy warrior more deadly than any hungering beast on this hostile new world…but whose eyes show a different sort of hunger when he looks at her.It was his last year of freedom:Uyane Meoraq is a Sword of Sheul, God’s…


Book cover of Philip's Rules

Vivian Murdoch Author Of Dark Hunger

From my list on darker dystopian omegaverse with a large dash of kink.

Why am I passionate about this?

I have been writing since I was in kindergarten. Granted, it started out with poetry, but words are still words. When it comes to omegaverse, I made sure to devour some of the great writers before I even stuck my toe in. The great thing about omegaverse is that you can put it in almost any setting, and it fits. I just happen to like dystopian, and now historical regency England, as my backdrop. I’ve been writing professionally since 2020, and I have never looked back once. This is my passion. This is my calling. This is what I’m meant to do.

Vivian Murdoch Why did Vivian love this book?

When I first started reading romance, I read nothing but historical. But then, I got bored with it because it all felt the same. That changed when I read this book. It was kinky and filthy, and still had that amazing historical romance mannerisms that I love and crave. I didn’t know books could be like this. I was smitten. Because of her, I fell back in love with historical romances.

Book cover of The Devil's Bargain

Aveda Vice Author Of Feed

From my list on short monster romances doing things differently.

Why am I passionate about this?

Monsters intrigue me. I’ve always enjoyed the weird and obscure – the creatures who are recognizably not human. Being a queer, autistic person, I’ve often felt as if I didn’t understand the world…or the world didn’t understand me. Reading and writing about monsters sheds a new light on the parts of myself that I was taught are undesirable. By conventional standards, the monsters in these stories are horrifying, yet they find people who love them and their monstrosity. Monsters get their happy endings – and I can get mine, too.

We all know the story: someone messes around with magic and ends up indebted to a demon. In this short, however, our main character is a queer Black man, and the devil that finds him won’t take no for an answer. For fans of Omegaverse, dubcon, and monsters that look like monsters, definitely check this out!

This book grabbed me from the moment I picked it up. It was dark, delicious, and one of the best mindf*cks I’ve read in a long time.

Once again, Addison Cain is on my list for omegaverse, but this time, it’s for a reverse harem omegaverse. Until this time, I had never read reverse harem, but there it was in all its intricate depraved glory. Again, very much on the dark scale, but I still devoured it. There really is no one like her when it comes to darkverse books. She’s literally the one I hold the standard for.

When I tell you this book took my heart and ripped it out, I’m not even joking. I knew it was a dark book. I went in with this knowledge, but knowing and knowing are two totally different things. This was my first foray into contemporary omegaverse and I was fascinated beyond belief. This is one of those books that kept me up all night, downloading the next just so I could get my fix and find out the end of the story. Some of the scenes still live in my head rent-free.

This was the book that broke my Omegaverse cherry. It was dark, raw, and unapologetic, and it left an impression. It’s one of the few reasons I write omegaverse today.
