Where did the book Breaking Dawn get its title?

Stephenie Meyer has stated in interviews that the title of Breaking Dawn was inspired by the following quote from William Shakespeare's play Romeo and Juliet:

"But, soft! what light through yonder window breaks?

It is the east, and Juliet is the sun."

In this quote, "breaking dawn" is used metaphorically to describe the arrival of Juliet, who is compared to the sun. In the book Breaking Dawn, the title refers to the arrival of a new day for Bella and Edward.
