'A mysterious craft docks unexpectedly on a space station in orbit around the Earth –could this be humankind's first contact with an alien civilisation? Eerily, the ship that sits silently in the dock is similar–with a few significant differences–to the Orion, a spacecraft launched from Earth into deep space 180 years before and never heard from again. What Senator Maya Russini discovers when she leads a team to board the ship will change her life, and the course of human civilisation, forever: five hundred life forms poised to wake from stasis. While they are genetically human, unnerving violet eyes and predatory teeth and claws suggest otherwise. And, as Maya comes to discover, they have no empathy, no memories, no names–and they don't know where they came from or why. She and the newcomers become pawns in a dangerous game between rival space stations desperate to get their hands on whatever technological secrets they and their spacecraft might hold.'
