OKAY, so figured out how to get the book to work. You need to get it BEFORE slapping her ass. Once you have it, you will carry it with you until she tells you to keep your hands to yourself. Go outside like if you were to talk to the aliens, and for some fucking reason THEN he will say he should put it somewhere prominent. To everyone who was struggling to figure out how to do this and has already been told to lower her morals; I am sorry, but you will either need to load an earlier save pre ass slapping, or start over. Fuck this game.
Edit: It appears even getting that step isn't enough. The flags on this quest are all fucked. I don't think there even is a proper way to do this.
Has ANYONE gotten this quest to finish?
Edit 2: Fuck it. Found a way to trigger the flags in JUST the right way I think. Saving you all the hassle.
