30 Pieces of Silver. Book 4. Trial by Sea

The 15th century. On the Iberian Peninsula, the Reconquista is slowly dying out. But the Catholic monarchs—whose fate is to unite the kingdoms of Castile and León, the Kingdom of Aragon, the Emirate of Granada, and the Kingdom of Navarre—have already been born and soon will be ready to announce themselves to the whole world.

And it would be good if, alongside them, there were a person from the future—his mission to find those very thirty pieces of silver that can change the entire world or, at most, a single destiny.
