The Bibliophile
Find all the books detailing the history of Knothole Island, or help another Hero to do so.
There are 10 books to collect in all, here are the locations (note: the books are not in order):
Knothole Island, Volume I - Off Gordon when you first enter Knothole Island.
Knothole Island, Volume II - Only tricky one really; In the ice shrine,
in the right room of the main circular chamber with the four triggers in front of the lighting bolts, just to the right of that, you can vault
down, pull a lever which drops a ladder which you follow to the book.
Knothole Island, Volume III - In the shrine on the second mission,
after you've pulled the first lever and entered the door with the
pressure pad. Next to that should be a breakable wall.
Knothole Island, Volume IV - As soon as you enter the Storm temple - on the right.
Knothole Island, Volume V - Off the right of the dirt track on the way to where you dug up the Sun Key.
Knothole Island, Volume VI -By the stairs next to the tavern after you've done "Big Freeze."
Knothole Island, Volume VII - As you exit the shrine at the bottom of the hill after you've used the fire totem.
Knothole Island, Volume VIII - Behind the one of the gravestones as you enter Knothole Island (on the left before the wooden boardwalk)
Knothole Island, Volume IX - As you exit the second shrine (in the
rain), it is behind a rock on the third bend (your dog should bark.)
Knothole Island, Volume X - After you leave the third shrine (snowing now), the book is on the right behind the rock.
