On the battlefield, as warring factions deal out death, young Mercutio chances upon the charismatic poet Dante Alighieri. In their desperate stand against the enemy, they inadvertently open a crack between our world and Faerie, literally changing the stars over Mercutio's head, and creating a mysterious presence who will follow Mercutio for all the days of his life.
With new stars come new destinies for young men who will travel to the ends of the Earth to honour the bonds of love and friendship.
As outcasts and exiles, Mercutio and Dante find family in a band of fighters called the Montecchi, near Verona. With his friends at his side, Mercutio will battle to change his stars, and to free the changeling upon whose fate hangs the future of the human world.
