For the first 40% of the book, I felt annoyed by the main character because she just seemed so immature and indifferent to the feelings of others. Also, I just kept being annoyed at the fact that the author chose to make the character 16 years old but also set the story on a university campus. 

The world-building was truly awful with many pages in a row of just straight exposition. It's really difficult to feel like this is a real-world and magic system when the information is presented so flatly.

However, the last 30-40% of the book really starts to get good and by the end, I actually liked the main character and felt like there was meaningful character development.
