In the second volume is about the complicated relationship between Jace and Clary, more secrets and the fight against the Shadowhunter Valentine, the apostates. To decide between good and evil is not easy and often it is not clear which character is on whose side.
In the third volume, we see for the first time Idris, the conflicts between Shadow Hunters, Valentine and Downworldern (werewolves, vampires, fairies, warlocks) coming to a head, there are dead, bloody battles and an important new character named Sebastian
All in all zweichnet the series for me by a pleasant mix of tension, horror, humor and sense of.
