Suitably apocalyptic ending to the original Merchant Princes trilogy, with refreshingly few interventions of luck along the way. The chapter at the end (you'll know which one I mean if you read it) is chillingly effective.
I do wish someone'd do an alt-history series with primitive electronics that isn't based on valves — it could have been the FET (or even something wackier, like magnetic amplifiers) that took off in this universe...
The next three volumes (one and a half volumes?) are currently under construction.
