The modern girl, named Hannah, thinks that moving to a new school will give her a chance to start over and make new friends, but she quickly realizes that she was wrong. The other girls in her class tease and exclude her, and Hannah feels isolated and alone. One day, while walking home from school, she discovers a hollow tree and decides to leave a page from her journal inside, hoping that someone will read it and understand her struggles.
The monk, named William, is a young man living in medieval England. He is training to be a scribe at the local monastery, and spends most of his time copying and illuminating manuscripts. One day, while on a break, he discovers a piece of paper in a hollow tree and is intrigued. He reads the page and is moved by Hannah's words, recognizing the pain and loneliness she feels, even though he lives in a different time and place.
William decides to write a letter back to Hannah, using the same hollow tree. He introduces himself and tells her about his life in the monastery, offering advice and encouragement. Hannah is surprised to receive a response and decided to continue the correspondence, finding solace in William's words and gaining a new perspective on her situation. They write to each other regularly, sharing stories and insights.
As time goes on, Hannah and William grow closer, and they begin to confide in each other more deeply. Hannah tells William about the bullying she's endured, and William shares his own struggles with doubt and faith. They develop a deep bond that crosses the centuries, supporting each other through their respective challenges.
Eventually, Hannah's situation at school improves, and she begins to make friends. She tells William about her victories, and he rejoices with her. William's own life takes a turn as well when he discovers a passion for art and creates beautiful illuminations. Hannah and William continue to write to each other, sharing their thoughts and dreams, and the hollow tree becomes a symbol of their enduring connection.
