Honestly, it was better than I expected. I especially liked the world building, it was done very nicely for a MLM fantasy. The plot twist (if I can call it that) wasn't as expected and I overall liked the story.

Despite having almost 400 pages, it was a quick read.
The plot was really great and for a celebrity-fan book, it was rather unusual (there's no romance between the two main characters, which is a fact I really like).
I adored the characters with my whole heart. Especially Angel, because as a fangirl myself, I could clearly see the reasons why she loved a band so dearly. Also, the question of fan culture and how far it goes was interesting.
Loved it!
