Then work your way from the top right most room to the bottom left most room reading any books you might have missed. If you've read them so far up to hear then you should just have the ones below left to read:
The GOAT Attraction.
A Distant Missive.
The Mystery of the Speedy Sheep.
Husky Business.
Neverwinter Naps.
You should have all the books read now. If not once the game is complete you can use chapter select and head into the Chalet chapters to re-read any you missed. When you're in the bottom left most map piece a cut scene will happen.
