Question

What's the quote by Shakespeare at the beginning of book III in Breaking Dawn?

Answer 1

Well, the Shakespeare quote isn't at the beginning of book 3, but at the beginning of book 2.

"And yet, to say the truth, reason and love keep little company together nowadays."

    William Shakespeare

   A Midsummer Night's Dream  Act 3, Scene 1

But, if you want the quote to book 3, here it is:

  "Personal affection is a luxury you can have only after all your enemies are eliminated. Until then, everyone you love is a hostage, sapping your courage and corrupting your judgement."

  Orson Scott Card
