It’s the year 1570. Fourteen-year-old Guido Callatta, son of a wealthy Venetian merchant, spends his free time roaming the docks, listening to the tales of gnarled old sailors, and dreaming of adventures at sea.

But his carefree life is about to change forever. Armies of Ottoman Turks threaten Europe from all sides, conquering Christian towns and forcing their people to convert. Moslem corsairs raid the coastlines at will.

In this historical tale of Catholic heroism, courage, and holiness, readers of all ages will be reminded that when the Faith is threatened, extraordinary valor may be demanded of any one of us — even the very young.
