The next time I log in I will finally be assigned the quest to find the book. Spoke to her every day for the last 2 weeks.
Does it really reset? I just assumed you had to speak to her 14 times total over time. It would be pretty silly, and pointless, to require you to speak to her every day with no breaks allowed. The dialogue doesn't even make sense like that. Nor does it make sense that you have to find the book the very same day she assigns the quest (after all, what if you had no idea where it was). I'll test it when the servers come back up (my plan was to talk to her and grab the book the first thing when I log in), but I would be quite surprised if missing a day reset everything (though I did have the thought that a server crash might reset it).
