Sixth and final book in the Merchant Princes series, sequel to The Revolution Business.

Everything’s going to hell in all three parallel worlds, our United States, the Gruinmarkt, and New Britain. The con­ser­v­a­tive faction of the world-walking Clan has launched a nuclear attack on the U.S.—and the U.S. is going strike back, hard. The only realistic option for the pro­gres­sive wing is to find sanctuary in New Britain, where the monarchy was recently overthrown in a bloody revolution.

Charlie Stross brings the series to a haunting, nuclear-fired conclusion.
