A Song in My Heart, the first book in a trilogy, is a historical novel set in the early 1900s in the United States, Mexico, England, France, and Italy. Alejandra Stanford is born into a privileged bi-cultural family in Minneapolis. Growing up, she and her artistic family intimately experience the intermingling of American, Hispanic, and European cultural influences, as well as formidable national events that challenge their lives; yet, Alejandra finds music is the perfect expression of her own artistic inclinations, emotions, and ambitions. As a young pianist and budding composer, she is affected by Minnesota's musical pioneers and resolves to become a conductor despite the obstacles.

When driven, sensible, and independent Alejandra travels to the great cities of the world in pursuit of her dreams, she falls in love with the music of legendary composers. Along the way, she will meet two men who are her match in ideals and intellect, each with the potential to bring fulfillment in very different ways. Ultimately, it is the passion for music and love which guide, inspire, and determine Alejandra's destiny.
