It wasn't bad. It was certainly entertaining. But even though it ended on a cliffhanger, I'm not tempted to continue with the series. 
The Idea of the story is basically the movie "The Game" with Michael Douglas, but with magic and in a circus-like atmosphere. Understanding that and being able to predict the general direction and idea of the plot made it much less exciting than it would have been for someone who didn't know, where this was going. It was a good rendition of that idea but the characters seemed a bit too immature for me to truly empathize with them. And thankfully I was never traumatized in the way Scarlett and Tella were. So I can't truly understand them. From an educational point of view, it's good to try to understand, what a person, who went through such trauma would feel. But I'm not sure that the author depicted that most truly and authentically and so I'm afraid that she didn't quite handle it with the care it deserved.
So I applaud her for including domestic abuse victims but I'm not sure she did the justice and that feels wrong. Like she used that for shock and as an excuse for flawed writing. 

All in all, nice idea, and a very fun aesthetic, but a bit too much thoughtless drama and a bit of a lack of self-awareness. 
I do not believe that I will continue with this series. At least not in the near future.
