Finished Sudden Death by Álvaro Enrique, it's bloody brilliant. Read it on a tablet and kept popping out into Wikipedia to look up all the folk and events he was describing: ranges from real tennis to Hernán Cortés to Henry VIII to Caravaggio, various popes & cardinals, battles, seductions, duels & beyond. Wondrous.
Now reading Chris. Priest's The Adjacent, which ain't bad at all.
