USA Today talks with Laura Sessions Stepp about her new book, "Unhooked."

The best part:

Q: Why do girls hook up ?

A: Young women are putting off romance and long-term relationships. To go with a guy means you've got to give up time with girlfriends, time spent on work, on your studies. Is the benefit of a relationship worth the cost? Many are saying, "No, not right now."
