Eva's nameday is coming up. And on that day, she'll become a Rival Heir. From then on, she'll be expected to try to kill her sister (or die in the process), so that one of them could take the throne. Eva's always been her father's favorite, but in this matriarchal society, her mother, the Queen, who, of course favores Eva's sister Isadore, would do anything to make sure that Eva doesn't get the throne. Including helping Isa with her magic while trying to keep Eva from accessing hers. But the throne is Eva's destiny. It's that, or death.
This was another instance of the plot being hard to describe, though that's mostly due to the fact that there are so many things happening in this book. It's pretty complicated. Not in a bad way - I really enjoyed it. The worldbuilding was very cool, I loved the khimaer. A lot of it was new to me, or a fun twist on a familiar concept. I loved the book's mythology. Something about it felt fresh. I also bizarrely really liked the middle part of the book - its full of layered mysteries, court intrigue, training montages and the right amount and type of romance. It's built on mutual and earned respect (and yes, hotness). There's a lot to like in this book, and it won't be the last by this author that I read.
That said, the beginning and ending were rote and felt a bit weak. The end, in particular, felt like it existed only to get you to read the next installment. There was no resolution, and it felt very rushed, especially after a story that was otherwise taking its time unfolding. I don't want to spend a lot of time criticizing what was otherwise a fun read - give it a go!
TLDR: This was so close to being really good, but it just missed the mark (rote beginning and ending, super strong middle and worldbuilding). I quite enjoyed it, nonetheless. 3.5 stars - I almost really liked it. :)
