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.
A inter-timline 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 between their respective timelines before it's too late?
