clown assassin?

Iron Sunrise

Charles Stross

Iron Sunrise is the sequel to Singularity Sky . This is a significant improvement over that work.
The main plot revolves around young girl known as Wednesday who uncovers proof of a plot by a group called the ReMastered that resulted in the destruction of New Moscow, a relatively low tech planetary system. As the ReMastered set events in motion to cover their tracks, Wednesday goes on the run. Rachel Mansour and Martin Springfield (from Singularity Sky) appear in another plot thread – New Moscow?s revenge against the (wrongly) suspected New Dresden government was to send slower-than-light
weaponry to destroy the planet. These ships can be recalled, or set on an irrevocable course by the remaining Muscovite Ambassadors – except they are being assassinated one by one and their authority keys taken.
Wednesday ends up on a cruise ship and in the company of Frank Johnson, a warblogger with reason to hate the ReMastered. Gradually these plots are drawn together with the realization that the cruise ship has been in port at every location that a Muscovite ambassador has been killed and Mansour & Springfield board the ship to investigate.
This is a well written and well plotted book. I really enjoyed it.
I’d recommend it to anyone would likes their science fiction.
