In the Kingdom of Kalyn, humans are good for two things. Hunting and owning.

Adina Barron was bred to serve the ruling-class vampires. Owned from birth by Blackwood House, her only desire has been to keep herself and her sister safe. But Adina harbors a dark secret. She possesses the power to turn her blood into a deadly poison that kills vampires. An ability she swore never to use until she learned that her sister was dying. After discovering that vampire venom can extend life, Adina has spent the last year risking exposure and execution to hunt and kill the creatures she was born to obey.

But desperation leads to foolish mistakes, and when she accidentally reveals her power to a mysterious stranger, she is forced to make a difficult choice. Use her ability to assassinate the Crown Prince or watch her sister die.

The decision is easy, and it’s not long before Adina manages to use her wits and cunning to embed herself into the prince’s life. But making the kill is not as simple as she anticipates, especially when fate seems hell-bent on drawing the pair together. And when whispers of a war start to arise, Adina realizes that there may be bigger issues than just saving her sister.

But time is closing in, and soon she will be forced to make a choice. Her sister? Her kingdom? Or her heart? Because one thing is clear, she cannot save them all.

Content Warning: violence, death

I saw this on Kindle Unlimited, saw it had good reviews and that it was a vampire book so I downloaded and I was not disappointed!

+ I love a good Vampire romantasy, but I would say this was more fantasy with a little bit of romance. In this world, vampires are in charge and humans are enslaved. Adina, belongs to Blackwood House and is a blood donor. But when she can, she’s killing vampires, so she can take their fangs because their venom has magic that can help her sister, Willow, who is sick. Adina will do anything to help her sister, which was one thing I admired about her. But when Adina’s ownership changes hands and the vampire Prince, Karius, wants her, her life changes drastically.

+ World-building is easy to consume, humans and vampires were in a war a long time ago. Vampires won and ruled and there are some humans that accept their fate, some who want to try to escape to a settlement where they can be safe, or are like Adina and trying to survive their rule. I did want a little more world-building though. There is also a new element to the story, which brought a little horror, which I found really fun. But what I really loved about the story was the twist and turns, there are so many things that happen and it kept me on my toes. The more I read, the more I could not put the book down! I like all the fighting scenes and I did predict some of what happened in the end, but it was still fun getting there. The ending was devastating!

+~ Adina is a strong character but one of those FMC’s that make so many mistakes and is so stubborn that it makes you want to shake her. Her mistakes put people in danger! I love that she loves her sister, it’s her only motivation in this world to save her. She has to train with some of the vampires when she is bonded to Karius because if she dies, he dies, so she eventually creates a found family with them. I was so invested in so many of the side characters! Karius is the typical gorgeous, powerful, shadow daddy vampire prince but I like that he has a lot of restraint where it comes to Adina and her stubbornness.

+ The romance is a slow burn, there is one spicy scene and I really was hoping for more, but that’s all we get and it was good! I do feel like Karius and Adina don’t seem to have many scenes together, which is actually fine because she’s growing on her own as a character. Plus fated mate books can sometimes be hit or miss for me but I like how this is slow, and the word “mate” isn’t thrown all over the story. They are reluctant mates but the bond is strong and the attraction was growing but I wanted more! Because Karius seems to fall fast for her but we don’t see them together enough for all the things he wants to do for her – he will burn the world down for her. I still ate it up, but I just wanted more.

Final Thoughts:

In the next book I want to see Adina grow, and maybe learn how to give up some of her stubbornness. I don’t know what is going to happen with the romance but I found this to be a fun, binge-able, addictive vampire fantasy. I can’t wait for book two!
