When a maiden is selected to marry the emperor, her journey to the palace will see her fighting both a spark of magical power and her growing feelings for her broody escort in this romantic fantasy duology opener, inspired by a true story from the Inca empire.
In the Amaru Empire, it’s considered an honor to be chosen for the annual harvest. But when guards stole Nina’s brother away, it devastated her family. So, when the guards returned for Nina’s sweet sister, she threw herself into their clutches instead. And Nina has spent every moment since then in the acllahuasi, a gilded cage where women are trained to become servants or wives.
When Kasik, an obedient lieutenant in Amaru’s army, is sent to the acllahuasi to retrieve the emperor’s new wife, it’s only the promise of his own command—and a chance to escape his controlling father—that forces him to accept.
Kasik has no reason to trust Nina, nor she to trust him. But, as they begin their journey, their chemistry is hard to ignore. Also hard to ignore? The tugging sensation of magic in Nina’s chest, awakening more questions than she can possibly answer as she travels with a handsome stranger to her unknown fate.


Content Warning: violence, death, sacrifice
World Building: Set in a fantasy world inspired by Incan culture, I love how lush the world building is with the different words (use the glossary in the back), the customs, religion, mythology and politics.
Characters: Kasik is sent by the emperor (his friend) to retrieve a certain young lady to be his wife. But Kasik isn’t given all the information and when he meets Nina, she is always fighting him. Nina is a young woman who is trying to protect her sister, but she’s taken to be the emperor’s new wife and she feels like she has no choices. She finds out she has powerful magic and later in the story her female rage makes it’s appearance and changes her from someone with no choices to being someone to be feared and deadly. I thought it was fascinating to see what she would do with her powers. There are some other characters that stood out like the empress and the emperor that lended to the political intrigue going on in the later half of the story.
Romance: This is a forbidden romance between Kasik and Nina. She’s retrieved to marry the emperor but on their harrowing journey together, they are attracted to one another. Kasik knows he can’t have her, and Nina knows there is not hope between them, but it doesn’t stop him from yearning for her which I loved. By the second half of the book he will do anything for her. There is no spice, just some really lingereing looks and thoughts about one another. But I still enjoyed it that way since they can’t be together and makes me want to know what will happen in book two.
Story: Kasik is tasked to retrieve Nina and we get to know both of them on this journey. Kasik is loyal to the empire, Nina is trying to save her sister and figure out her deadly magic powers. I feel like Nina’s character goes through a few transformations and it was very interesting to see go from powerless to powerful and what she chooses to do with that power. I enjoyed the world-building a lot though I had to use the glossary to understand some things. And I really enjoyed all the political intrigue that was happening when they are all at the palace.
Narrator: I did have a hard time getting into the ebook because of all the words I had to look up in the glossary but once I started the audiobook I was sucked into the story! The story has dual narrators and they both were great, but at times I felt the male voice sounded softer than the female – her voice was crisp where his sounded just softer.


Final Thoughts:
I found the world-building lush and really loved the political intrigue especially in the second half. The narrators did a great job keeping me invested in the story and it makes me want to read book two to see what happens with Nina and Kasik!
