I believe this was fixed as of version 1.0.107.0
Are you saying that she didn't sell you any books? Not even a pair?
This game is weird... I've patched to 1.0.107 last night and I was able to buy 2 sets of books as explained before. I don't know how this function, it may have something to do with hiring/dismissing henchmen. I'm just happy that it does, for me, at least.
It would be good to know if this works for someone else as well.
And no, I didn't install any mods or altered the game in any way.
