A new ice age... and a shocking discovery... will change humanity forever.

In the near future, a new ice age has begun. Humanity stands on the brink of extinction. Desperate for answers, scientists send probes into the solar system to take readings.

Near Mars, a probe spots a mysterious object drifting toward the Sun. Is it the cause of the ice age? Or could it be our only hope of survival?

With time running out, NASA launches an international mission to make contact with the object. But it isn’t what anyone thought. In the dark of space, alone, the team makes a shocking discovery that will change the course of human history—and possibly end it.

Four hundred years from now mankind is strung out across a region of interstellar space inherited from an ancient civilization discovered on Mars. The colonies are linked together by the occasional sublight colony ship voyages and hyperspatial data-casting. Human consciousness is digitally freighted between the stars and downloaded into bodies as a matter of course.

But some things never change. So when ex-envoy, now-convict Takeshi Kovacs has his consciousness and skills downloaded into the body of a nicotine-addicted ex-thug and presented with a catch-22 offer, he really shouldn't be surprised. Contracted by a billionaire to discover who murdered his last body, Kovacs is drawn into a terrifying conspiracy that stretches across known space and to the very top of society.
