Two sisters, separated by oceans and global conflict, are bonded through music and love in this gripping novel based on true events from World War II.

The year is 1941, and in the Philippines, Caramina Grassi dreams of training in Italy to become an opera singer like her older sister, Rosa. But as war erupts, her world is shattered, forcing her to cling to the music that has always been her refuge. When her family’s lives are threatened and they are forced to flee to the jungle, she comes to understand that music is more than comfort. It becomes a muse that fuels her courage, sacrifice, and unwavering focus on the light.

Meanwhile, in Florence, just as Rosa Grassi’s long-awaited opera debut arrives, Mussolini tightens his grip on Italy. Drawn into la Resistenza, the underground resistance, Rosa feels lost in a fog of deception that clouds everything she thought to be true. In a time when family or friend could be foe, Rosa will learn that performing isn’t just for the stage. Facing a devastating betrayal, she must decide how far she’s willing to go to protect the one she loves.

Inspired by true events, In the Light of the Sun is an unforgettable story of sisterhood, hope, and the enduring power of music to uplift the human spirit—even in the darkest of times.
