Gabriella and Evangelia Betarrini time travel to fourteenth-century Italy, where they live in castles they've seen as crumbling ruins, become swept up in historic battles, and fall in love with handsome knights willing to do anything to keep them alive. They returned to the present to save their father, just short of his tragic death, and now all of them return to the place that holds the girls' hearts, medieval Italy. But remaining there means facing great risk as the battle for territory wages on and the coming Black Plague looms.
