Una never asked to be chosen. But when the Heart of Harmony diasappears—the living force that keeps every world in balance—eleven children from different worlds must rise to protect the balance of all creation. Armed with nothing more than her courage, her loyal Cavalier King Charles spaniel Lady, and a sharp-eyed crow named Watcher, Una steps into a universe of floating islands, ancient guardians, and a shadowy enemy known as the Hollox.
Full of magic, friendship, and the fight for harmony in a fractured world, The Hollox: Heart of Harmony is the first book in a new middle-grade fantasy adventure series by Mel De Pablos.
