Invisible sun
(Book)

"A Tom Doherty Associates book."

"The alternate timelines of Charles Stross' Empire Games trilogy have never been so entangled than in Invisible Sun-the techno-thriller follow up to Dark State-as stakes escalate in a conflict that could spell extermination for humanity across all known timelines. An inter-timeline coup d'état gone awry. A renegade British monarch on the run through the streets of Berlin. And robotic alien invaders from a distant timeline flood through a wormhole, wreaking havoc in the USA. Can disgraced worldwalker Rita and her intertemporal extraordaire agent of a mother neutralize the livewire contention before it's too late?"--,Provided by publisher.
