Every day, Antonio Vivaldi composes a new orchestral piece, and every day, the orphan Candida transcribes Vivaldi's masterpiece into sheet music for the Invisible Orchestra. Nobody notices Candida or appreciates her hard work.

But one day Candida accidentally slips a poem she wrote into the sheet music and the girl so often behind the shadows gets recognized for her own talents. Vivaldi really did have an Invisible Orchestra made up of orphan girls he taught to play. This beautiful book pays tribute to their inspiration.
