This must-read story is a confident, action-and-violence-packed thriller and future classic noir SF novel from a multi-award-winning author. 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.
