Deluge (River of Time, #4)

The Bettarinis and Forellis have found rich fulfillment together in medieval Italia. But after fighting off countless enemies, they now must face the worst foe of all. As the Black Death closes in upon them, threatening everything and everyone they hold dear, Lia and Gabi–and the knights they love–must dig deep within to decide how they might remain safe…and if they need to risk it all in order to truly live as they’re called.
