The puzzle text from page 227 (bottom right) and page 235 (bottom right) reads:
Magic ink can have many forms.
At times it is gone, at times it transforms.
For the final riddle just both is perfect,
Sometimes you can see it, sometimes it is wrecked.
Find every clue then you will know,
Start right at the front, and magic will show.
Sometimes it is dark sometimes it’s bright,
Sometimes you are wrong, sometimes you are right.
