Wow. I got that drop, took a look at it and promptly clicked "destroy" when I saw it was a book and taking inventory space.Guess I should have paid more attention. :P
Haha OH NOOO, you got all the way to the book and deleted it?! Thorvald whyyyyyyyy!It's okay though, if you've done all the previous quests up to that point you should be able to use someone else's book to trigger the next quest in the chain. Just gotta find a friend who's willing to grant you access to their house to interact with it. (Which may be rare, since you 're CLEARLY a rampant destroyer of literature! =P)
