"I would, please," Karla said, nodding. "I haven't decided to rest on my laurels in the wake of what happened in Rinoa's world or anything. And it's always fun to argue with books."

Which Karla did. Often out loud. Sometimes just with scribbles in the margin with helpful comments like 'Pompous jerk' and 'remove your head from your ass first.' Don't worry, Ender. She wouldn't write in yours.

"Speaking off, have you been reading the books I gave you? Any of them strike your particular interest?"
