The Best Alien Romance Books

1. Obsidian – Jennifer L. Armentrout

After the death of her father, Katy moves to West Virginia with her mother for her senior year of high school. She wanted to sink into her boring but safe life of reading books and working on her blog.

Daemon and Dee Black are Katy’s neighbors. Daemon is beautiful with brilliant green eyes but also very rude and arrogant. Dee swears to Katy he only acts that way to be protective, but she’s not so sure about it.

When Daemon rescues Katy from an attack one night by stopping time to save her, he marks her. Katy realizes he and Dee are aliens (alongside many others in town) hiding in their town from a galaxy of enemies intent on stealing their abilities.

The alien romance Obsidian is swoon-worthy, and Katy and Daemon have a sort of enemies-to-lovers fantasy romance complimented by endless banter between the couple. 

2. Choosing Theo – Victoria Aveline

Aliens abducted Jade. The Cae is a reptilian alien race that kidnaps her to deliver her to an unknown person for unknown reasons.

The Clecanians, a matriarchal society of aliens, rescue her. The terms of her rescue are she must choose a husband and live by the Clecanian’s laws and orders for one year.

The men on the planet outnumber women 20-1, but they are brought up in husbandry schools to ensure they’re treating the women with respect and making them happy.

The Choosing ceremony is where the women on the planet get to select their husbands, and they’re mandatory for men to attend if they wish to start a family.

Theo is a scarred mercenary regarded as a beast by most women on the planet and has never been chosen. Jade sees something in Theo and chooses him. He can’t help but think that she has other motives. 

Choosing Theo has an incredibly unique take on the world-building of the alien planets that stands out in the genre.

The relationship between Jade and Theo will have you rooting for a happy ending and kind of wishing it was you on the planet instead of Jade.

Megan is drowning in the middle of the ocean one second and being pulled out by the laser beam of an alien spacecraft the next.

Her rescuer is Tren, a mercenary turned space pirate who took a job to bring some aquatic life to his client.

Tren is annoyed with Megan, who he views as a barbaric creature far below what he is used to on the evolutionary spectrum.

But she is oddly enticing to him. The pair begin a relationship on their journey through space on Tren’s spacecraft but deny any real feelings for each other.

When Megan is put in danger Tren is forced to face his true feelings and rescue her.

7. Dark Horse – Michelle Diener

After stumbling upon a legendary battleship with his crew, Captain Dav Jallan searches through it to discover an AI robot named Sazo and a strange alien being called Rose.

The Tecran, who owned the ship Rose was being held on with Sazo, are looking to start a war to get it back.

Dav suspects that Rose and Sazo might not have been the only creatures remaining on the ship and worries there is a giant game being played.

Dark Horse focuses a lot on the science fiction aspects of an alien romance and has a high-stakes plot.

Corsairs: Adiron is another installment in Ruby Dixon’s expansive intergalactic universe.

Corsair Brothers is the name of this series, but this book features several cameos from Dixon’s other beloved characters.

11. Chosen – Stacy Jones

When Lily is working late in the fields of her grandmother’s old farm tending to the cows, she’s unknowingly abducted by them.

The alien animal poachers had no need for her, so when they discovered a human aboard the ship, they dropped her off on a strange planet with no means of survival.

She was destined to die, that is, until three Frrar, Tor, and Arruk find her and rescue her from an impending floor.

The three aliens had been searching for a mate to accept them with no luck until that point. But something about Lily is different and they know she’ll accept them.

12. Saving Askara – J. M. Link

Victoria is a doctor aboard the starship Phoenix and less than impressed by the alien species they’ve encountered so far – which have been non-sentient microbes and organisms.

Until they come in contact with a ship full of demon-like aliens escaping their home planet due to a threat to completely destroy it by one of their enemies.

Victoria is invited onto their ship to tend to the wounds of the aliens and acts as a liaison between them and other earthlings.

Aderus is the general of the aliens and is distrustful of the humans at first. But over time, he learns to trust Victoria and realizes his feelings for her are growing.

This is a first-contact story, so it sticks to many of the typical alien science fiction conventions, but the romance is more realistic than some other stories.

The trepidation the lovers have before admitting their feelings only makes their passion stronger.

Saving Askara is an excellent read for people who like a slow-burn romance.

13. His to Claim – Taylor Vaughn

The Xalthurian aliens are using the planet of New Terrhan as a breeding ground for their race.

When a woman turns 21 they mate with an alien and if the child is a boy it’s taken back to be raised by the men on their planet as warriors.

Little did she know the man she fought was the prince of the Xalthurian, Kel D’Rek. He promises to return for her when she turns 21 in exchange for her nephew’s freedom.

This is an alien romance that has a lot of dystopian elements to it. It is a darker story that deals with many real-world issues that we still have today.

So, His to Claim would be a good read for anyone who likes alien romance books rich with symbolism.

14. The Krinar Experiment – Charmaine Pauls

This book follows Drako, an alien on a secret mission on Earth that crashes in his ship and sustains serious injuries.

He’s captured by the South African government and experimented on for a month before escaping. 

Ilse is a nurse tasked with helping him recover from his injuries while he’s there.

Drako can sense the connection between them but can’t separate his feelings of love from the betrayal he feels with her hand in his captivity. 

The events during his captivity lead to a war with the Krinar, and Drako takes Ilse when he’s back on his ship to get revenge on her for betraying him.

The Krinar Experiment is a continuation of the Krinar Chronicles by Anna Zaires.

Zaires gave Pauls’s consent to add to the world she built in the original series.

This book can be read as a standalone but will make you want to read the entire collection of Krinar novels.

Doom is another post-apocalyptic, romantic, dystopian sci-fi book, so for readers who enjoy the end of the world and doomsday tropes, this is a great choice.
