In the distant Vega system, Perry Rhodan and his crew are trapped on a strange world that is under attack. To have any hope of saving the Ferrons, they must reach the aliens' leader in the central city, but getting there will be a treacherous road filled with betrayal and self-sacrifice.

Now that humanity knows it is not alone in the universe, alien threats are coming from all directions and in forms no one could have imagined...
