“You're my sister," he said finally. "My sister, my blood, my family. I should want to protect you" - he laughed soundlessly and without any humor - "to protect you from the sort of boys who want to do with you exactly what I want to do."

I guess we're all just lucky my father faked his own death before he got to the raping and pillaging part of my education, or no one would be safe.”
