Okay let’s just sum up the bad in brief points:

The plot - if that’s what this mess could be called - was bad.

So many sentences made little to no sense, with bad grammar and scenes and conversations contradicted like the author had lost her flow or forgot who said what. There was also constant use of ‘the other girl’ and ‘the other boy’, I kept thinking another person randomly joined the scenes and kept screaming for the author to use the characters names or pronouns. 

All the boys are slim with long hair. While I would appreciate a change from many YA fantasies having many characters with unearthly fitness. This is ridiculous, their trained Shadowhunters and half demon creatures, they’re allowed to have muscle. It was quite constant.

I still don’t like Jace, he’s a mean character, yet I’m supposed to see him hiding his emotional damage with endearing arrogance? No he’s mean and only at the end of this book starting to seem like he’s changing. The Mortal Instruments was originally meant to be a trilogy, so that’s at least 2/3rds of the story line with a unlikable main character.

My pet hate in books/films/tv shows is characters experiencing and displaying emotions only when that plot will prove valid. By this I mean, a character only experienced emotional pain when something would later be proved to have definitely happened, but seemingly felt nothing when the same thing happened but would later be revealed as being a false alarm.

Lastly, oh the casually okayness with incest?! At points Clary and Jace are okay with incest between them. Probably best suited to Game of Thrones and not books read by young teens, just a thought.
