Best Alien Romance Series to Binge: 5 Sci-Fi Romance Worlds to Get Lost In

Sometimes you do not want one alien romance.

You want an entire planet.

You want several couples, recurring characters, expanding worldbuilding, dangerous politics, impossible creatures, fated mates, protective warriors, and enough books waiting behind Book One that your weekend quietly ceases to belong to you.

That is the beauty of a great alien romance series.

You get the romance payoff of each couple while the larger world keeps growing around them.

So if you are looking for your next binge-worthy sci-fi romance obsession, here are five Miranda Martin series built for exactly that purpose.

1. Red Planet Dragons of Tajss

If you want the biggest world and deepest binge, start here.

Red Planet Dragons of Tajss begins when a human generation ship is destroyed and the survivors crash on Tajss, a brutal desert world beneath two red suns.

The planet is already inhabited.

The Zmaj are powerful humanoid alien warriors with horns, wings, tails, scales, and protective instincts that become extremely inconvenient once human women enter the equation.

The humans are trying to survive.

The Zmaj are trying to understand the humans.

The planet is trying to kill everyone.

Romance seems inevitable.

The series grows far beyond the first crash. Settlements form. Relationships between species change. New threats emerge. Old secrets surface. Human and Zmaj families begin reshaping the future of the planet itself.

Each full-length novel delivers its own romance and happily ever after, while the larger Tajss story continues across the series.

You’ll love Tajss if you want:

Alien dragon warriors, fierce heroines, fated mates, survival romance, forced proximity, found family, dangerous alien creatures, crash-land stories, political conflict, and a huge interconnected world.

Start small

Begin with Dragon’s Baby, where botanist Calista meets Ladon after surviving the destruction of her ship.

Or accept your fate immediately

The Tajss Starter Vault contains Books 1–10 plus a bonus story, giving you eleven ebooks at once.

Eleven ebooks.

Two red suns.

Absolutely no expectation that you behave responsibly afterward.

2. Draconian Warriors

Want more spaceships, galactic conflict, dangerous politics, and powerful alien warriors?

Meet the Draconian Warriors.

This series follows human women and the winged alien warriors whose lives collide with theirs across a galaxy shaped by tyranny, war, captivity, rebellion, and survival.

The Draconians are strong enough to fight empires.

This does not mean they are prepared for human women.

It rarely does.

The series moves through captains, commanders, outcasts, rebels, barbarians, pirates, warriors, and queens, with each romance revealing another piece of the larger conflict.

There are eighteen books in the complete series, which makes this particularly dangerous for readers who use phrases such as:

“I’ll just read one more.”

You will not.

Start with Alien Warrior’s Captive Bride

Alien Warrior’s Captive Bride begins with a human woman leaving a dying Earth through the Alien Brides Program.

Then raiders attack.

She crashes.

Larok finds her.

He is winged, powerful, protective, and convinced an ancient bond has chosen her as his mate.

She has opinions about this.

Ready for the full binge?

The Draconian Warriors Complete Series contains all eighteen books.

That means eighteen alien romances, eighteen happily ever afters, and one extremely endangered TBR schedule.

3. Survivor Brides of Tajss

If you like your alien romance darker, more dangerous, and centered on people who have already survived far too much, try Survivor Brides of Tajss.

This series returns to Tajss later in the larger timeline.

The world has changed.

Survival is still difficult, but the threats are different. Human, Zmaj, and Urr’ki communities are trying to coexist while new dangers begin surfacing across the planet.

These books lean strongly into wounded heroes, fierce heroines, emotional healing, forced proximity, dangerous missions, alien mysteries, and relationships that have to be earned under pressure.

Start with Bride of the Scarred Alien

Bride of the Scarred Alien pairs Kara with Drazan, a scarred Zmaj warrior haunted by devastating loss.

Everyone thinks Kara is too weak to survive Tajss.

Drazan thinks protecting her means making decisions for her.

Both assumptions are about to have a very bad time.

The romance is built around two wounded people discovering that strength can look very different from what everyone else expects.

Want the entire arc?

The Survivor Brides of Tajss Complete Series includes all six books.

This is a great weekend binge if you want something substantial without accidentally committing the next month of your life.

Although I make no promises.

4. Red Planet Jungle of Tajss

Perhaps desert Tajss is not dangerous enough.

Excellent.

Let’s add a jungle.

Red Planet Jungle of Tajss expands the Tajss universe into a very different part of the planet.

The environment changes.

The dangers change.

The romances do not become more reasonable.

This ten-book series gives you another group of interconnected alien romances while opening up new regions, characters, threats, and pieces of Tajss history.

If you like discovering a familiar universe from a completely different angle, this is one of the most satisfying ways to keep exploring after the main Tajss books.

Start with Riley’s Dragon

Riley’s Dragon begins this section of the world.

Or skip the part where you pretend you are going to pace yourself.

The Red Planet Jungle of Tajss Complete Series contains all ten books.

5. Red Planet Fated Mates

Sometimes the specific craving is simple.

You want:

Fate says that one.

Then you want to watch two people argue with destiny for several hundred pages.

That is where Red Planet Fated Mates comes in.

This ten-book series leans hard into the emotional side of fated-mate romance.

The characters deal with grief, identity, leadership, fear, trauma, trust, survival, and the unsettling possibility that someone from another species may understand something about their future before they do.

The bond may be immediate.

The relationship is not.

That distinction matters.

Fate can point.

It cannot do the emotional work.

Start with Healing Her Heart

Healing Her Heart follows Desiree, a widow who believes loving again would betray the husband she lost.

Then Rhuklyv arrives.

He is enormous, winged, patient, and somehow capable of looking at her grief without asking her to erase it.

This is less about fate replacing love and more about whether someone can believe they are allowed to love twice.

If that trope is your weakness, you may also like my guide to what fated mates means in romance.

Ready for all ten?

The Red Planet Fated Mates Complete Series gives you the full ten-book binge.

Which Alien Romance Series Should You Binge First?

If you want the largest, most immersive universe, choose Red Planet Dragons of Tajss.

If you want galactic war, winged warriors, commanders, rebels, and eighteen books waiting for you, choose Draconian Warriors.

If you want wounded heroes, survival, danger, and emotional healing, choose Survivor Brides of Tajss.

If you want more Tajss with a completely different environment and another ten-book adventure, choose Red Planet Jungle.

If you want fated mates front and center, choose Red Planet Fated Mates.

There is no wrong answer.

There are only varying levels of sleep deprivation.
