I stripped my novel clean of all quotes, all outside references. Below are the quotes that littered the chapters as I went.

I probably missed some...

"Just a reflection, it's just a glimpse, just a little reminder, of all the what about's, and all the might have, could have, been's. Another day, some other way, but not another reason to continue; and now you're one of us. The Wretched."
-- Nine Inch Nails – The Wretched
