In essence, Queen Elizabeth I sent The English Armada to Iberia in 1589 while England and Spain were at war. Christoval Alvarez, the main protagonist, was Jewish by birth, but was forced by the Spanish, along with her family, to convert to Christianity. In this installment, Christoval is a young woman physician (posing as a man) who has also been recruited into the secret service by Sir Francis Walsingham. Christoval's life is complicated, to say the least.
The non-fictional players, admiral of the English Armada, Sir Francis Drake, and general Sir John Norreys failed their mission, leading to the defeat of the English fleet with heavy losses in lives and ships. In this installment, Christoval witnesses the mistakes of Drake and Norreys as she/he hides their gender, attends to the suffering of the wounded, pursues her/his mission given by Walsingham, and seeks out his/her family who had remained in Portugal.
So, quite a lot goes on in this novel. I should have brushed up on European history before reading it, or perhaps I should have read the previous installments of The Chronicles of Christoval Alvarez. Without a backdrop, The Portuguese Affair requires a lot of scrambling to decipher the who's who and why of events. The writing is clear, fortunately, and the major components come together--even if one is not up to speed on 16th century European history. For full appreciation, I recommend starting from the first of The Chronicles, unless the reader is already familiar with its history. My overall rating is 3.5 stars.
