It is incredibly difficult when a best friend gets sick, and even harder to understand when they do not get better. After her beloved classmate and friend Rudi passes away, a young girl struggles to process her feelings of sadness and loss. To honor his memory, she and her schoolmates come together to build a special project: a beautiful, peaceful pond situated right next to the big oak tree in their schoolyard. They hang a bright hummingbird feeder that Rudi himself had made, hoping to bring life and beauty to his memorial. When a delicate hummingbird suddenly appears to drink from the feeder, the children find a gentle sense of comfort. Based on a true story, this poignant and beautifully illustrated narrative provides a compassionate look at grief, the healing power of community, and the ways we can keep the memories of those we love alive forever.
