- Reviewed in the United States on June 25, 2021Format: KindleVerified PurchaseLoved Crina's character. She is loyal, kick butt, but can get hurt as well. She's not some oper the top superhero. The story line itself is a different concept on the paranormal. I like the different abilities of the characters. I like the world building so far, but I hope it expands and book two. There is steam in this book. Story is told from FMC POV. Ends in a little bit of a cliffhanger, but this entire story is gonna be one long ongoing arc. The story was fast paced and extremely interesting. Can't wait to dig on more with the characters and the story in next book.

“There are others you can hire,” I offered. “Quality people who’ll get the job done, whatever it is.” “Quality people…” His knuckles brushed against my cheek. “But, Crina, I only want the best.”

⭐️⭐️⭐️⭐️ (3.5)
Crina is a demon assassin. She’s super fun and sassy and I enjoyed her humor and relationships with her friends.
The plot of this first book was a little weak but I like where it lead the other books in the series!
If I’m being completely transparent... I didn’t read this for the plot.
I read this book for Breccan, a demon lord, and Ilya, a vampire. While there is a plot to the books, I really enjoyed the heavier focus on the romance.
(I’ll be straightforward, as I usually don’t put spoilers in my reviews, and say that she doesn’t choose, and she doesn’t give them up. There is no love triangle - bless you, Gaja).
Crina longs for freedom, and Breccan, in a way, offers that up to her. They work together in Shadow World to uncover who is leaking top secret information from Breccan’s business. There’s a deeper plot than the one first presented and I really enjoy how it progresses! I immediately picked up the second when I finished. Ilya plays a larger role in the second book but we do meet him in this one. He’s my favorite of the two. This series is very spicy and though the writing is so different from The Shadowfire series I still love Gaja’s writing.
* Badass female lead
* Amusing humor - I laughed so much
* Underlying depth and character connections
* Spice 🌶🌶🌶🌶 (4 out of 5)
* Easy, enjoyable read
* Ilya. He’s precious.
* Breccan. He’s more dominant.
- Reviewed in the United States on June 23, 2022Format: KindleVerified PurchaseCrina is an assassin who has been hired to find an amulet for some witches. This book is her adventure to finding it only to have it slip through her fingers. She’s hunted down and nearly slaughtered only to find love with someone else. A new daemon lord is in the picture and they bond. She does some work for him successfully. Then she gets handed a letter from her dead father that tells her a lot more about herself. And it’s a mystery who her parents are.

- Reviewed in the United States on January 4, 2021Format: KindleVerified Purchase4 stars for Shadow World by Gaja J. Kos. This is book one in the Shade Assassin Series and also my first book from this author. I am not sure how this author has escaped me for so long but that will not be the case anymore. I am in love with the world Kos has immersed me in. Crina is part demon/ part something else but a total bada**. She is an assassin and a private investigator of sorts. She lives more in the mortal realm than in the demon world. I like how she does and takes what she wants and makes no apologies for who she is. Breccan is a sexy demon lord who comes to Crina for help. Ilya is a vampire who runs the crime world for demons, he and Crina used to be together. Reiner is a werewolf assassin who has it out for Crina. I enjoyed all the sexy scenes, and boy are there a lot. I feel this book gives us the run down on everyone and sets up the story for the next books. I will say that I love Breccan and Ilya and I am not sure which one I like better. I feel like if I say too much, I could give something away and the suspense and not knowing what to expect is what made this story great.

- Reviewed in the United States on July 9, 2020Format: KindleVerified PurchaseA very nice beginning in what looks like a promising new series. The MC is a strong badass with logical decision making abilities that she uses for her advantage every time I really liked this book and I'm hoping the second one is just as good.
- Reviewed in the United States on June 2, 2021Format: KindleVerified PurchaseGood start to the series. I love how brutal she is, it’s perfect. Not a wishy washy assassin. And her and Breccan are steamy, and I hope things progress with them.

5.0 out of 5 stars Brilliant Read
Format: KindleVerified PurchaseWhen I had this book come to me from free booksy, I was unsure of whether it would be good or a flop.

5.0 out of 5 stars Shadow World
Format: KindleVerified PurchaseThoroughly enjoyed, the story flowed easily. You have a badass FMC who can hold her own and who doesn't drop everything for a bond. She continues on with her job as an assassin and obviously enjoys the work.

5.0 out of 5 stars Definitely worth reading!
Format: KindleVerified PurchaseI really liked the plot of the book and the various characters. What bothered me was the main characters (Crina) reaction everytime there was danger ahead. I mean she is supposed to be a badass assassin but then is always scared to her bones if someone appears who she didn't expect. But other than that, a really good book!

3.0 out of 5 stars Interesting
Format: KindleVerified PurchaseNearly gave up on this book it is clumsy for the first third with an unappealing heroine who swore all the time for no reason but that lessened and the plot picked up along with a good classic love interest. so 2 stars for beginning and 5 stars for the end
