How we cite our quotes: (Part.Chapter.Paragraph)
Quote #1
The man watched with impassive interest as Elias screamed again and turned to run. He never reached the door. Agramon surged forward, his dark mass crashing down over the warlock like a surge of boiling black tar. Elias struggled feebly for a moment under the onslaught—and then was still. (Prologue.23)
We begin the book with a pretty graphic violent act, as a demon kills an unsuspecting warlock. What's even more horrific is that Valentine does nothing. This kind of violent sacrifice is exactly what he needs.
Quote #2
Jace had wanted the oblivion of fighting, the harsh diversion of killing, and the distraction of injuries. (1.1.12)
Jace doesn't know how else to deal with his problems. He's the type of guy who needs to break stuff to vent some anger.
Quote #3
[Maia] remembered the dark shape exploding out from behind the metal merry-go-round, the huge wet wolf body knocking her into the mud, the savage pain as its jaws clamped down on her throat. (1.2.4)
In this world, it's impossible to experience any sort of peaceful change. Maia's werewolf curse has a violent beginning, just like Simon will experience later when he becomes a vampire.
