Releasing Darkness: A Fated Mates Demon Paranormal Romance

Rate this book
A mysterious note sent Sasha to the one place she vowed hundreds of years ago never to return to.

She never expected to encounter her mate.
The mate who had been held prisoner and tortured by one of the High Generals of The Underworld for thousands of years.
The mate who was one of the four brothers that the entire demon race seems to have forgotten.

The problem was that Varos didn't look at her like she was his fated mate.
No, the only way she could describe the way he looked at her is with utter hatred and repulsion.
She couldn't even blame him for feeling that way since it was her father, the High General, who sent her running all those years ago.

If they managed to survive their escape through The Underworld, Sasha swore to herself that she would deliver Varos to his brothers and never bother him again. No matter how much she had grown to love him.

Another great book from Demons Within series and can’t wait for the next book!

I loved their pet Max, reminds me of the cute Imp from the movie Strange Magic.

This book lost a star cause I dislike the tropes where they are banging each other while they’re hurt & healing. Also banging during the middle of a war zone. Like come on stop banging each others brains out when it’s not necessary haha

I was eagerly awaiting the next part of the Demons Within series. This time the author took me on a dangerous journey to the Underworld.l. The heroes of Releasing Darkness are demons: Sasha - the daughter of the High General and Varos a.k.a. War. The story begins intriguingly with a mysterious letter containing clues from the Fates that will allow FMC to find another of the brothers Verek and Valen. However, this task is associated with a great risk, as Sasha's return to her home world may end with her death at the hands of her own father.

Unfortunately, despite a good start, I was unable to get into this story. In my opinion, everything seemed forced and a bit rushed. I didn't feel like the story was developed enough to actually keep my interest. The characters also weren’t interesting enough to keep the story going.

When I read a book, I like the feeling of being another companion in the story. This time, however, I felt like a spectator who watches everything from the sidelines without much involvement.

This book was my introduction to the Demons Within series and now I can’t wait to go back and read the first two and I definitely look forward to reading the next book. While I didn’t have any issue reading the book as a standalone, I would recommend following the authors advice and reading the books in order, to get the full picture of the characters, specifically the brothers and their mates. Though there was some slight word/phrase repetitiveness, the story itself was well written and the depictions of the people and places pulled you into their world. This is a fast paced journey for Sasha and the third brother (Veros) with an almost instalove mate connection. I also loved the dual POV which allows the reader to experience the story through the eyes and minds of each character.

Sasha was 17 years old when she left the Underworld because of her father, the High General. When she crossed, Varek helped her and they became friends. 300 years later she receives a missive that she needs to rescue one of the two brothers still missing from her father’s dungeon. She goes alone even when she’s terrified of her father.
She is a succubus but not happy about it and tries to be the opposite of her father, an incubus that always uses his demonic powers on others, always hurting them.
She’s kind and compassionate, and she’s been trained by Varek and is a badass!
Varos was imprisoned when he was 20 years old and the High General has been torturing him since then.
When Sasha steps inside Varos's cell she discovers they’re fated mates and that he hates her just because of whom her father is. When he clears his head a little and starts to see her and not who fathered her, he regrets his initial reaction to her. They start to fall for each other while trying to cross to the human realm.
There’re more clues as to why they lost their memories and what is to come.

Details:
- DV. She didn’t want to be like her father (a cruel incubus), and he was thrown into the dungeon before he could be with anyone.
- Epilogue only a few weeks later.
- HFN. There’s still one brother's book left.

Releasing Darkness book three is an enemies-to-lovers journey that brings together two fated mates in another engaging Demons Within series entry.
Sasha and Varos are the lead protagonists in a story of mystery, intrigue, danger, emotion, spice, family, and a love that grows from the depths of hatred.
A nicely written Paranormal Romance with imaginative world building that will bring the reader along on an amazing adventure through the underworld realm and back.
I very much enjoyed the well crafted characters and the story I found myself immersed in.

This is the third book in the series which follows Sasha and her fated mate Varos. Theirs is an enemies to lovers relationship which is firmly rooted in hatred despite the fact that they are mates. This is very much to due to who Sasha's father is. Their paths have been harsh and separate but maybe it is time for them to finally come together?
The world building is great and you are sucked into the story and the underworld along with the fantastic characters. There is intrigue, action, danger and a huge mixture of emotions.

This is an amazing read!
I loved Sasha as she was a powerful, strong woman ho wasn’t afraid to do the right thing. Plus she had such an emotional time and managed to survive. Varos had gone through his own emotional rollercoaster and managed to come out sane is a miracle. I thought that the chemistry between these guys was soooo hot and their scenes together sizzled.
Once I started reading I could not put this down. This is a super 5 star read!

she’s done it again

Such an amazing book. Sasha and Varos love story is miraculous. They have to overcome so much. Not only their own personal struggles but outside forces that want to destroy them.
This one might be my favorite so far. While I’ve read them all, you can JUST read this one. But I PROMISE you’ll get hooked and go hunt down the first two books. That’s just how good R. Sullins is!

Am I to believe that the h is a badass? She’s not the feminine fatal that she’s supposed to be, she doesn’t accept who she is and is literally a virgin for a sex demon. She can’t even kill a hell bunny without help and don’t get me started on the rescue journey where she didn’t even pack food or water or feed beforehand. The 360 that the H did was wtf, the author couldn’t even dragged the angst instead they fucked almost immediately while still in danger mind you.

This is my first read by this author and I absolutely loved it! I really wouldn't call this an enemy to lovers as it was too fast paced in the love department for that. I loved it none the less! Even though this is the 3rd book in the series I still understood the plot and the background without reading the other books.

This is the third book in the series and with each one I am drawn more and more into the world and the story. I love the main characters, they are so well written and have so much personality that they literally come to life with the story. The emotional rollercoaster I experienced while reading was so worth it. I eagerly wait to see what R Sullins will come up with next!

Danger everywhere

I love Sasha and Varos' story. Getting Sasha's story was a treat. Getting a better understanding of her upbringing and how she came to be who she is, was heartbreaking.
They are another powerful couple in this world. I can't wait for the next book!

I absolutely love this series and this book is a great addition. Sasha is such a badass. I feel for her and all the stuff she has been through, especially with her family. In this story, we get to meet the 3rd brother aka War. At least this time he remembers everything so we get a better picture of what is happening with the underworld. The only thing I wish is the General got off too easily. I can't wait for the next book!!

Book review:
Releasing Darkness by RSullins Rogue Readers

I think this was my favorite out of the series so far, it is the third book. Why? Because Sasha is so strong and brave for going back to a world that wasn't meant for her. She was sent on this mission anonymously to basically save one of the 4 demon brothers, who could help reclaim the demon Underworld. She didn't realize when she set out to find this brother, Varos, that he would be her fated mate. They also had a cute little protective creature along the way. As they fight battles, to get to the portal to Earth, we see their relationship transpire into something beautiful. But will it stay that way, and could they accomplish what fate set out for them to do? 5 stars
