For five years, sleep has been anything but restful. Her dreams don’t simply feel real. She wakes inside them, experiencing everything from sinking ships and prehistoric worlds to beautiful cities where someone always seems determined to kill her. Doctors call them nightmares. Therapists search for meaning. Her family thinks something is wrong. Then one person asks a different question: What if she could control where her dreams take her? Suddenly, going to sleep might not be something to fear. It might be the beginning of the greatest adventure imaginable.
