This was just...not for me.
The MC is a witch who is also a demon hunter. She also has had a demon trapped within her body ever since he attempted to kill her sister years ago. She lunged at him and he became trapped in her body somehow. It's never really explained how.
That was part of the problem I had with this book: the world building is a bit sparse. The MC was also a bit abrasive for my personal taste. I think she was meant to come off as kind of sassy and tough, but it didn't work for me.
There's also two potential love interests, and ugh...I'm not feeling love triangles at all these days.
