I only reached 14% but it was absolute rubbish. The plot doesn't make a lick of sense.
Kai's assistant, a human, is found dead. Since she was human, the human police are the ones investigating. As it turns out, the detective investigating her death is her brother. I don't care if this is fantasy or not, never in a million years would that be allowed. And yet, in Magic Nights it's not a problem. There's no raised eyebrows, no comments from characters or even an explanation from the author or Sera as to why this isn't a problem.
In addition to that, Kai doesn't seem to be bothered about his assistant's death. He's more concerned about how it will impact business. I knew Kai wouldn't be the crying sort but he would at least show some sort of emotion over the loss of his assistant who, if I recall correctly, had worked for him for many years.
That seemed very out of character to me.
Then Kai and Sara deem it their place to break the news to the boyfriend. They do this because they suspect he might have killed her. But they never discuss the boyfriend's motive. They just think, "Oh, she had a boyfriend? He killed her. Case solved."
