Well the only thing I really enjoyed in this book was the atmosphere it created at certain scenes.
The premise was really good; a young girl with a trauma from her childhood going for a performing arts summer camp circus. The character development was not good and after a long exposition part on who, why and how everything happened I was left disappointed.
I won't say this is a horror read, unless you consider movies like final destination horror. Honestly, the supernatural aspect really ruined it for me, it felt a cheap and a not very well explained way for the plot.
