One of the Best I Have Read In A While
First of all, who did your cover, because it is gorgeous. Honestly, I love it, especially how it looks like your main character.

I'm gonna get the bad right out of the way, the speed is way too fast in the first 10 chapters. I found it very distracting on a few levels. It kind of left no room for world development, like I couldn't picture being in the world. It also felt like you were rushed, like the pacing was way too intense. I could see if this was a stream of consciousness and you wanted to get the idea on the page as fast as possible, but it would probably make more sense if you drag some things out. Like when Avalor was torturing Kelsie, there wasn't any real reason for us to care about Kelsie because the pacing made it so we couldn't get to know her.
As for the positive, I love the concept of the plot. Avalor's attitude as a stone cold witch (excuse the pun) is a great way to paint the character, and the short backstory you gave us for her really gave a small connection to her. However, maybe you can break up the chapters more with that backstory. Show us how Avalor became powerful, and feared.
Overall, the story definitely has a great plot, a wicked character, and I love the amount of emotion you put into her.
