Is there any guide for the book locations? I know in another thread you said one was time sensitive, which I'm guessing is to do with the one that is constantly stood in front of. I've managed to find 14/15 and it's driving me crazy.
Viewing post in [SPOILERS] Achievement Guide
I would suggest crowd-sourcing the book locations. Would you want to create a new thread with "Spoilers" in the title and you and other players can list the locations in which the books have been found? I feel like this would be more satisfying and fun for players because they discovered the locations themselves and worked together towards doing so.
(The book locations is a little different from the hidden achievement guide, because I was planning to give the option to reveal the hidden achievements anyway in the next update of the game.)
