And now I'm stuck with the damn thing. I always thought it was just the "Fetch Me That Book" quests that bugged out but apparently not. I was hoping I'd be able to trick the smith in Dawnstar into taking a second copy of "Night Falls" but sadly such wasn't the case. I sure do wish I'd have known that this book, that wasn't even in a chest, was going to get stuck forever!!! C'mon Bethesda fix these things already!!!
