Katy and her little brother have a place like that, an old tree near their house, where they have gone many times to escape from the fights their mom and dad have. But one evening, they encounter a wise old owl at the tree who takes them on an unforgettable adventure. Along the way, they meet many strange creatures and learn an important truth about their role in their mom and dad's lives.
