Dr. Fe del Mundo's devotion to her profession is clearly yet dispassionately rendered from the point of view of an observer who is a child. Details of her achievement are brought out in natural settings—the hallway leading to her office documenting her career in photographs or a dinner conversation between the child and her parents. The book has an uplifting theme shown without sounding preachy and pedantic. The title suggests the sound of a beating heart- a gift shared by all - thus gently disputing the child's original claim that her younger sister is "different".
