After a routine job goes sideways, interplanetary smuggler Jack Kind and his crew are forced into a deal with a dangerous politician transporting cargo from a military installation to a drop-off near the sun. It stinks like a setup, and may be connected to rumors of an alien craft discovered in the Kuiper belt. When the double-cross is revealed, and the cargo opened, the crew find themselves defenseless against a threat unlike any mankind has faced before. And they soon realize they aren't just fighting for their own lives, but for all life in the solar system.
