You can print out the book from HERE (12 pages +1 cover). Cut out the pages and glue them back-to-back, so they will have two sides just like the pages in a real book. Use glue sticks in order to avoid deforming the paper. Perforate holes to tie the book together. Glue the cover to a white sheet of cardboard. Glue the rest of the pages together as follows: 1 to 2, 3 to 4, 5 to 6, etc.
Then you can start coloring 🙂
