Overall I really enjoyed this relatively obscure historical novel about the great Catholic monarchs, Ferdinand and Isabella of Spain. It's a shame that I couldn't give it a better rating, but I'll get into that in a minute.
Ferdinand and Isabella are two of the most significant figures in the history of Reformation era Europe, although many people are not aware of their history. When Ferdinand came to the throne in Aragon and Isabella came to the throne in Castile, the Iberian peninsula was divided into the three independent and hostile kingdoms of Aragon, Castile and Portugal. The Islamic kingdom of Granada thrived at the southern end of the peninsula, and the kings of France had succeeded in keeping the security of the Christian nations of the peninsula in a state of instability. Not only the Ferdinand and Isabella unite the kingdoms of Aragon and Castile into a single kingdom of Spain, but they managed to nullify the French and Portuguese menace on the borders, drive the Moors from Spain after 700 years of war, and they even managed to liberate the island of Sicily from Turkish invaders and destroy the Turkish fleet in Africa before they could mount an invasion of Malta. The two literally turned two of the weakest nations of Europe into one of the greatest Christian powers in history. And, if that were not enough, they also funded Christopher Columbus's voyage to America, opening up a new age of exploration in the New World.
Schoonover is one of the best historical novelists I have read who dealt with Spain's golden age. He actually understood the times of these two great monarchs, including the threat of the Moors and the challenge posed by the prosperous and influential Jewish population of Spain. British writers who deal with Spain tend to treat the Spaniards as religious fanatics who loved to murder Jews. Schoonover, who is American, does not show that tendency. If anything, he is too apologetic of the Spain of the time. He describes the origins of the Inquisition but makes light of it. He glosses over cruelty that Ferdinand and Isabella displayed, turning a nation with a large non-Christian population into a nation that was almost completely Christian. They didn't do that by being kind - they expelled the Jews and Muslims from Spain and confiscated their property. They also placed great demands on the people in the form of taxes and military conscription to support their continuous wars.
Schoonover's worst sin in this novel is his lack of lively prose. His characters all sound the same in their dialogue; they all use this flowery language and act the same. The characters are shallow. Although Schoonover does a good job of portraying Ferdinand and Isabella themselves, the other characters really don't have personalities. There aren't really bad guys in this novel, other than political or military rivals that the reader doesn't really get to know. All of this makes for a tedious novel.
Overall, this is a good novel, and I would recommend it for someone who is interested in the Spain of Ferdinand and Isabella and who is willing to slog through the tediousness.
