Yes I am aware that Hiro did say that he wants FT to be Lighthearted compared to RM. but really, looking at them both now, the only real difference between the two in story aspect is the amount of deaths that has happened.

What I said has nothing to do with the tone of the story, far from it, it is about assuming things could lead to tragedy or catastrophe, if Lucy knew if the book said that what I described then she would have burned the book there, but after reading it all the way to the end and finding out what the hidden message was, she knows for a fact that she cannot burn it. Because it is the letters that Coby's father wanted to send to him.

She knows what his mind was so she would know what to expect from his book so of course she would find it strange, but she wouldn't just burn it without knowing what it was. That is the point of it all, don't judge a book by its cover.
