Current reading is Pavane by Keith Roberts. A 1968 alternate history novel--strictly speaking, a collection of linked stories, all of them set in Dorset, England--it posits a world where Elizabeth I was assassinated and the Spanish Armada conquered England, leading to the broader suppression of Protestantism and Catholic supremacy throughout Europe and its colonies. As a result of various papal bulls, many forms of technology, notably electricity, are suppressed, and the English still rely on steam power for transportation in the mid-20th century.
As you can tell from that brief summary, the novel rests on certain implausibilities. I don't really mind, though. Roberts was a superb writer (and an equally gifted visual artist, by the way) with a deep love for rural England that comes through in his prose. Besides, it's just nice to enjoy an alternate history that doesn't rely on one of the three shopworn premises in that genre (Nazi victory in WWII; Confederate victory in the American Civil War; a Roman Empire that never falls). Variety is the spice of life, after all.
