City of Bones
How we cite our quotes:
"You're just a slimy Downworlder who didn't even care that all those years [my mom] treated you like a friend—like an equal—and this is how you pay her back!" (20.115)
Without even realizing, Clary seems to view Luke, a werewolf, as less than a real person because he's a Downworlder. She should probably think about that for a minute before she writes the guy off completely.
