Shadows: Awakening

I got this on my first playthrough as Kalig so you don't need to find Evia's notes. Actually I think you don't even need any notes at all. The achievement popped for me when I got the last book I was missing which was "The Chronicles of the Order of the Veil, Volume III", but I still had around 20 notes missing. I didn't get the duplicate for the last book so I would say duplicates are not needed.
