It is the summer of 2019 when Thilda's world falls apart. The pain in her leg is not growing pains, but in fact a rare form of cancer. The revelation is followed by a period of operations and tough cancer treatments. She is forced to accept a new reality: trips to hospitals, treatments, and unbearable pain. But suddenly, something unexpected occurs. A chance encounter at her hospital leads to an unexpected friendship. Thilda begins to paint, take pictures, selfies, and talk about her days with her new friends. The result is a moving book about a unique young girl's journey with cancer, about her family's unfailing support, and a strong bond of friendship.
