My conclusion is that the European society that judges Daisy so harshly was actually afraid of her because she is manipulative and selfish. She will do any thing to help increase her social position. She is ruthless and that scares the other people. So In short, the europan society is actually afraid of Daisy because she is manipulative and selfish.
It's The lightning thief, The sea of monsters, The titan's curse, The battle of Labyrinth, and Percy Jackson's Greek Gods. (That is the sequence of the book series.)
