A Clash of Cymbals

Chronologically the last of James Blish's Cities in Flight series, The Triumph of Time (UK title A Clash of Cymbals) goes out with a bang, literally. The stakes? Nothing less than the end of the universe itself. This final entry of the series is a more cerebral book than the rest and I got entirely swept up into the different concepts Blish was presenting. I absolutely loved it!
