Seven-year-old Leo Harrison has everything a child could want-except the one thing he needs: his parents' time. When the family moves into a sprawling, century-old estate on the outskirts of town, the silence of the massive house only amplifies Leo's loneliness. His parents, driven by high-stakes careers, leave Leo to the care of the garden and his own imagination.
Everything changes the day Leo finds an old wooden swing under a weeping willow. There, he meets a young girl in a pristine white robe who calls herself Seraphina. While she looks his age, Seraphina is a spirit who has called the estate home for hundreds of years. Bound to the grounds but gifted with a protective heart, she becomes Leo's secret guardian. From comforting him during midnight thunderstorms to magically intervening when schoolyard bullies go too far, Seraphina is the sister and best friend Leo never had. As Leo grows from a lonely boy into a successful man, he realizes that Seraphina's presence was a divine grace. But as he prepares to start a family of his own, the time comes for his ethereal guardian to finally answer the call of the heavens.
