Alien Warriors' Obsession: A Dark Sci-Fi Reverse Harem Romance

by M.Q. Rush

Top of my apocalypse survival list?
Don’t get caught by alien brutes.
…Guess what I went and did?

Thanks to my little rebellious stunt, now I’m chained up, stripped down, and being ogled like I’m the galaxy’s hottest snack.

Drayzok aliens roll in packs of threes, and they mate in them, too. As soon as these three lay eyes on me—on my thick thighs, wide hips, and curvy body—they decide I’m their new obsession.

Do I want them? No. (Okay, maybe yes. Shut up.) Do I trust them? Absolutely not.

It’s twisted. It’s wrong.

I’m not just their captive anymore. I’m their obsession. And they’re not letting me go until I scream their names.

Alien Warriors’ Obsession is a dark, high-heat reverse harem alien romance. Featuring a snarky, curvy heroine and three possessive alien warriors, this read is explicit and addictive. Please heed the trigger warnings and read with care—not everyone can handle the heat with this much darkness.

This is the first book in the Reverse Harem Alien Invasion series. Each story follows a fierce, plus-sized woman and three dominant, sexy aliens. Perfect for readers who crave smutty, high-stakes monster reads that push boundaries with zero mercy.

'When she was fighting back against those men on Earth, she didn’t yield. It’s an admirable trait, even among my kind.
She’s fire, that one. Fight and fury. She sure seems angry with me and my trio. I don’t need to understand her words to hear that she’s spitting mad.
The manuals claim that it’s normal for human females to show resistance this way. Just part of their usual human mating rituals.
This one is sure putting on a good show of it, though. If I didn’t know any better, I’d think she truly hated us.'

I loved this book. It was such a fun reverse harem adventure and my first full novel by this author. As I love their work, I was very excited for it.

Great world building and wonderful characters. I loved Quinn and her alien triad Zegran, Thalor, and Korvan. She was sassy and snarky, tough and a fighter. I liked her sense of humor. I liked that the three aliens all had distinctive personalities and qualities. And we soon learn they are very misinformed about human "mating rituals" from their manuals, and the language barrier didn't make it any easier, of course. But it did keep things interesting. Was it only a misunderstanding, or was being misinformed intentional? I was completely hooked to this story.

I liked the dynamic between them and the way their relationship developed. And the chemistry was sizzling. This story was a fast-paced and I couldn't wait to see how it would all turn out. 5 stars

This story is quadruple POV, well written and edited, and a dark, spicy, male alien triad (Zegran, Thalor, and Korvan)/female human (Quinn), sci fi erotic romance. I enjoyed Quinn’s fighting spirit and skill, as well as her perseverance and determination. I enjoyed that she worked to convince her males to act on behalf of others as well as her. I enjoyed Zegran’s confident leadership that allowed for input. I enjoyed Thalor’s enjoyment of technology and his joy in sharing with Quinn. I enjoyed Korvan’s physical prowess and his training skill. I enjoyed the darker, erotic intimate scenes, specifically the way that Quinn enjoyed them. I enjoyed that the males wanted her to be an active participant and actively submit, not be overwhelmed or scared. I enjoyed the world building and set up for future stories, which I hope will emerge soon.

I received a complimentary copy from the author and this is my voluntary honest review.

I feel like there's a book started out really good all the way up until the time that Quinn was captured. After she was captured I got a serious case of the ick. And that continued all the way up until she got the translator. After she got the translator things got better. But to be honest what should have took me a couple hours to read took me a couple days because I kept quitting the book and going and reading something else and then coming back and reading a little bit more. Because there was just areas of the intimacy that were completely unbelievable and it made it hard for me to engage with the book.

Quinn is living in what she thinks is the end of the world and she fully believes it’s screwing her over. The one thing that is consistent is going into Estelle’s sad excuse of a shop, the only thing close to retail left. She brings things for trade and to get new supplies. She also hears about the latest rumors and gossip. She hears about when and where women are being abducted.
Alien Warriors Obsession is a great read, very interesting. Lots of spice and darker elements as well, a read for 18 and above. The characters and storyline are well done and worth the read. Grab this book and enjoy this five-star read.

I really loved this book. I love a good Alien abduction romance and that what I got here. The feisty heroine, and the 3 aliens. The story was really interesting and it had a very interesting world. How they felt about her from the start and how they doubt the 'manuals', boke the rules to communicate with her was wonderful.
I loved the way they stood by her and fought for all human females was brilliant.
It was well written and I really hope that this is a start of a series. I would definitely read more of them.

A really informative story. Learning what you have been taught is a lie. I really enjoyed the story. Some humor, great sexy times and fighting for what's right. There has been an apocalypse on Earth and then aliens, the Drayzok arrive looking for women to mate. The Drayzok mate in packs of three. Quinn gets caught after fighting off human men catching and selling women, The aliens, Zegran, Thalor and Korvan learn that everything they have been told is a lie after getting a translator for Quinn and actually be able to communicate with her. What will happen now?.

Curvy self sufficient female becomes kidnapped by aliens whom mate in triads, three big males to one female. They follow the manual for mating with a human female, and find out that the manual might not be completely truthful. Some dark aspects in the beginning, but a fun read with a good prefice and plot.

What really bugs me are the smut, every time I cannot figure out how they do what they do, I have read and reread passages several times to figure out who is where and how, and I just can’t. Sometimes because there’s just cannot be to very big aliens behind the same female pounding her from behind in each hole at the same time. Just not possible.

“But you have to mate with three men for every woman? Why’s that, are there not enough Drayzok females?” “Correct,” Zegran says, his expression darkening. “Many cycles ago, our females began to prefer each other’s company over males. They became increasingly reclusive. It created... challenges in our society.” “That’s why you started taking human women,” I say quietly. 

?????????????????????????????

Wooooooow was not prepared for such blatant homophobia what the fuck

Needless to say, I stopped reading at this point.

Dystopian, dark and dirty!

Alien Warriors’ Obsession is a dark, scorching hot reverse harem alien romance. A strong willed curvy heroine that and the three possessive alien warriors that find she's way more that they thought and that the norms of they society and what they assumed to know about human females was twisted to favor their liders. Well written ,with a good world building and charismatic characters. The interactions between the characters, the clash of wills and chemistry is delicious. This story is hotter than hell but pushes boundaries so check the TW.

This was savage
Raw
The power of submission is beautiful
I can’t wait to read more😳🔥😍🤗🔥😍🥰🤗🔥😍

Most of MQ Rush’s books that I’ve previously read were standalones, dark and smutty, enjoyable for a quick read. This one was…different…. The beginning to an awesome series I hope…there’s filthy poly sex, alien anatomy, but also a bunch of action, intrigue and a good plot🥰🤗🥰🤗

(But definitely read the trigger warnings first).

If you enjoy reverse harem romance with some dark themes this book is for you. The dark romance was mixed with sweetness which I enjoyed. I do like the fact that the main female lead was curvy because there is not a lot of books out there that do that. I also liked her strong personality. The description of the aliens were beautiful and the culture that was created for them was interesting. I hope there will be more and focus on other characters because I am curious about this series and hope for more.

What a ride, what a read! Thus book is hawt and steamy and dark so watch your triggers.

The plot was original and exceptionally hawt. World building was excellent and well thought out. The characters were what drove the story. The heroine delightfully snarky and the alien MMCs were so very appealing, spicy and dominant. Can't wait for more alien invasions.

Grab a copy, kick back and enjoy!.

The first story in the "Reverse Harem Alien Invasion" series. It's a dark, high-heat reverse harem alien romance that I found to be an exceptionally well-written and compelling start to the series. The story introduces Quinn, Korvan, Thalor, and Zegran, with a storyline that culminates in a very satisfying happy ending.

Quinn is just trying to survive in a world that's fallen apart, with few women remaining. She's always on the lookout for the gang that kidnaps women and sells them to anyone. That's how she ends up being captured by three dominant aliens who believe she is their mate. This is an intense, super-spicy book with excellent characters. I enjoyed reading it a lot.

Well written story, I recommend reading this book, If you're looking for a steamy, fast-paced sci-fi romance, I will read more books from this author.

[Becky Poirier · Rating 3 out of 5]

Okay

Its an okay story...I find it hard to get past the dominating power displacement that often feels way more like abuse that an authentic loving relationship

[J H Beard · Rating 5 out of 5]

What can be worse than being taken from your home planet by three large (but sexy) aliens? Oh, I don't know how about not being able to understand each other? Not only that, but the aliens also have a lot of misconceptions about earth females and their s3xuality.
A lot of hot times that will get your motor running.
