Gabriella and Evangelia Betarrini are just two normal American teenagers. Normal except for the fact that they time travel to fourteenth-century Italy, where they've lived in castles they've seen as crumbling ruins, become swept up in historic battles, and fallen in love with handsome knights willing to do anything to keep them alive.
They've returned to the present to save their father, just short of his tragic death, and now all four 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. Can they convince their parents to stay and leave behind everything they've worked so hard to accomplish? And will the girls sacrifice their futures in an uncertain past? Or in facing death head-on, will they discover life as it was always meant to be lived?
