Book excerpt: After a diving accident, thirty-seven-year-old Ramie Phillips is waking up, trying to understand a voice in the distance: "Wake up!" It's her mother. "You're going to be late for school again. I'm not writing a note this time." Transported back in time to the eve of her eighteenth birthday, Ramie's experience is the the fantasy of every woman who's ever thought, "If I could go back in time, knowing what I know now, I'd do things so differently."
