I am trying to make an animation of a book. To accomplish this I attached each page and the front cover to an armature. However, when I rotate the armature that controls the front cover, the cover rotates too much.
I have attached an image of the book before and after the cover is rotated, as well as the blender file.

How can I get the cover to rotate the same amount as the armature?
