Caveman Aliens #18
Caveman Alien’s Cage
He tied me up and put me in a cage. I should hate him.
So why can’t I look away from his twitching pants?
Morfan’ox is the most striking warrior in his caveman tribe.
Supremely confident, eight feet tall, with bright green stripes and muscles from here to Earth, he moves like he owns this deadly alien jungle.
I’ve barely talked to him, but he’s always on my mind.
But his tribe and mine are enemies. I can’t go near him.
So when he caught me with his lasso and put me in a cage, I did my best to escape. I’m not going to be a plaything for a tribe of woman-less virgin cavemen.
The bulge in his pants moves when he looks at me through the bars of the cage. I know he keeps something highly exotic in there. And my own body betrays me with a hot surge every time his eyes shoot blue lightning at me.
But if he thinks that this Earth girl will be impregnated by a grumpy, dinosaur-whispering single father like him, he’s in for a surprise.
I know his weak point. And I’m going to hit it as hard as can...
Caveman Alien’s Cage is the eighteenth book in the Caveman Aliens series of science fiction romance novels. It’s an alien abduction single father romance between a cranky caveman alien and a feisty girl from Earth.
The books are complete stories, but should be read in order for maximum enjoyment.

este estuvo mejor que el anterior y fue nuevo (y muy raro lo del hijo) del MMC. también fue interesante ver que ahí ya una protagonista se va a una aldea y vive ahí porque hasta ahora no había pasado y , sinceramente, me cuesta creer que ningún hombre de la aldea piense en hacerle algo a ella.

I will drop almost anything to snatch up the next Caveman read and this book was no different. Can’t believe we are on book 18 and theres still so much life and unknowns on X’ren. Here we meet a single dad and it couldn’t make me happier to see a caveman in this role and take his job so seriously. Raising a child for the cavemen really consists of the village raising the child. But hero Morfan’ox is not 100% on board with that concept and instead spends the majority of his time with his son. I think we all know the feeling of seeing a doting and loving father, it really just does something to the insides 🥰🥰 With war on the horizon between disgruntled tribes, Morfan’ox has his work cut out for him caring and protecting his son while also teaching him the ways of the world. Throw in a human female to really shake things up and you get the idea. Another great read but I’m looking forward to more of the different women and tribes from previous books across the planet meeting and exploring more of X’ren. It’s so amazing to see how far they all come on the planet but I’d love to see them all working together and really making this place a new and better home. The possibilities are endless on such a scary and wild planet.

This was another fascinating, totally engrossing read from Calista. Her world building skills are so sharp you feel as if you’re actually there. Besides the world of xren she’s created with alien dinosaurs and kidnapped earth girls and alien cavemen, there’s the romance and it was epic!
Morfanox was an awesome hero: he was strong and protective and saved the heroine more than once. Yasss, please. Tap into my primal cavewoman brain when a strong male who clubs away danger was what kept my female ancestors alive! He’s also smart and funny and curious. And even tho he has a son, he’s a virgin! Introducing one of the cavemen with a kid was a cool twist. The cavemen give their tadpoles into a part plant, part animal, 100% alien thing called a lifegiver, which essentially grows a baby for them. This is how the planet keeps repopulating the cavemen. It was endearing to see morfonax with his son—he fought with himself to show him affection, to spend time with him as the caveman culture frowns upon a father being too close to his kid.
Capree was a great heroine. She was sarcastic and resourceful and sweet with an edge. Letting down her guard with morfonax and allowing herself to trust him, to become close with him was a great journey. She helped encourage him to be a better version of himself and to be a better father. My only complaint is that this needed a better epilogue, farther out, with babies or a baby of their own. That was a let down. Other than that, I loved every second of this book. It was great fun!
Safe. Both virgins. There’s threat of OM, as other tribesmen want to kidnap heroine and SA her. The hero saves the day. No sharing or cheating or abuse. HEA but no real epilogue

Capree and Morfan'ox were friendly before the neighbouring tribes went to great lengths to try and secure the girls for themselves. Now, a chance encounter when Capree tried to sneak back for some of the Earthlings belongings, leads to chase through the jungle.
Morfan'ox is a new kinds caveman. He is hands-on with his son, for one. He'd rather study the multitude of life on Xren than just kill it straight away - hence his little compound. His relationship with Kendar’ax is so sweet. He understands the reality of Xren that he could be taken from his son at anytime and he needs others to look after him. But he also hates the thought of him learning from anyone else.
Kendar'ax is just like a mini-me of Morfan'ox. He's animal daft and is wise beyond his age. He took to Capree in no time and Capree realises early on that these two cavemen are package deal!
I love the stories in this series. Are they a bit over the top and out of this world? Yup, keep 'em coming!

Calista Skye once again brings us back to the planet Xren. In this book Capree gets to see Morfan'ox again. She hasn't seen him since they had to leave the soup can. But he has been on her mind and in some pretty hot dreams. She also meets his son,
Kendar’ax. Kendar'ax will steal your heart. He is very wise for only being right years old. He is a lot like his father. A lot happens in this story and it causes Capree to question Morfan'ox and his character. Perhaps he is not the good person she thought he was. Is he?
I love everything this author writes. The Caveman Alien series is truly the best of the best. It is so much fun to read. I absolutely love it.

Such a fantastic story!
Morfan’ox is such a unique male. He’s in tune with his surroundings, doesn’t kill unless necessary, and he’s very protective. I love the way he helps his son learn. He’s young, but just as protective as his father. Kendar’ax is simply adorable!
Capree is quite a woman. She fights being captured (more than once), she’s strong spirited, and loving. It doesn’t take long before she appreciates Morfan’ox for all his fine qualities. I laugh when Morfan’ox pretends he knows about the things that Capree mentions from earth.
Do enjoy this wonderful story in the Caveman Alien series. This is the best so far, in my opinion!

Le voy a dar 2 estrellas.
Creo que es el primer libro de aliens que leo... este año.
Es el número 18 (creo) de una saga, honestamente no voy a leer los anteriores. En las sinopsis que leí de los demás libros creo que no me pierdo mucho en el sentido de que no hay una historia general que se vaya desarrollando y se entrelace al pasar los libros. Fue una historia fácil de leer, rápida, sin mucho drama en general. Se conocieron antes, en este libro se enamoran, pelean contra los malos, ganan, se quedan juntos, fin. Me hubiera ENCANTADO ver un epílogo donde tuvieran bebés y demás, pero entiendo que no se puede por la historia

Very good
This was a very good story. I enjoyed this one a little more than the previous one. Characters were different than the usual type. That made for a better story. I enjoyed the child character being raised by the village but with his actual father involved in his upbringing. The Life bringing plants are fascinating and I am eagerly waiting to learn more about them and the secrets they hold.

This is one of those series that keeps getting better and better. Capree and caveman (Morfan’ox) final have their story. The Telaxi tribe is similar to all of the tribes on Xren. Morfan’ox is different from the cavemen in his tribe. Capree is doing a good deed when she is captured. Story is filled with longing, hope, acceptance, and love. It’s best to read the other two books before this one.
Received this ARC in exchange for an honest review.

again… amazing…
This series is addictive… each book has this wonderful, dangerous life. Passion for life and honor…. And love.
I loved the back and forth teasing between the “caveman “ and “woman”. Great fun.
Yes… this is very simplistic in story and development… not Shakespeare level… but so very refreshing. I look forward to the next book… and the development of the “Ploods”.

Awesome Book!!!
I really enjoyed reading Caveman Alien’s Cage(Caveman Aliens Book 18)!!! All about Capree a twenty-eight year old earth girl & Morfon’Ox a caveman warrior of the Telaxi Tribe. On this planet women are needed to keep the population growing. So the tribes are willing to fight and kill each other to get there hands on a female. Read about Morfon’Ox & Capree and see if they have a future!!! Lots of emotions and toe curling incidents occur. Definite Read!!!

Was very surprised after reading this book as I really enjoy this series. However, this book felt different than the others - it felt rushed and “shallow” somehow. I didnt connect with the characters like I usually do and sometimes doubted it was written by the same author, edpecially the last half of the book! :/

Love me some caveman
I have to admit I somehow missed the story of what happened to the first group of women on Xren. This new groups stories are just as good. The characters are fun, intelligent, sexy, loyal and interesting. The stories are good. The monsters are scary & the villains are dastardly cowards. Its all good. 😍

adventure, humor, love, and steamy hot romance with awesome characters? You won't be disappointed in any way when
reading this book and a must buy.

I love this series. Capree and Marfan'ox seemed such an odd couple during the first half of the book. But then they slowly started to mesh as a couple. Their adventures and interactions made the second half of the book great. The jungle became less scary because of his insight of the creatures. Then his son and his father made the ending very happy.

Caveman Alien's Cage
Morfan'ox still saves animals in need and through diligent observations knows lots about the bigs and smalls. His son aids him and when the other tribe tries to kill his father he kills one. Capree a human woman is caught by Morfan'ox and trouble ensues.

Cowboy Caveman
I’m thinking this maybe my favorite caveman yet. I just love this story. The smartest caveman and most self aware are rising to the top in these stories. I love that the renaissance of Xren is starting to happen. More, please!

Yes more!
I'm thoroughly enjoying this series and I can't wait to see what new things we will experience next. My biggest question is, will the first group we read about meet this group in the near future? I would love that!

I love this series
I love this series. Its fun and I like how things happen all over the planet instead of just one spot. Because why wouldn't there be more people and different cultures around a planet? It big enough.

Love these books
Morfan'ox and Capree are destined for each other. But they are a lot of trials first. We meet Morfan'ox's son and father. We meet the bad guy again. And we meet some different animals. Very good read. Enjoy
