Once upon a time, Adrana and Arafura Ness dreamed of travel, adventure and wealth. Now they own the space sailing ship "Avenger", but along with the ship, the sisters inherited the monstrous reputation of its former owner. Forced to wander through the dark outskirts of inhabited space, they come up with a plan that will allow them to return to hospitable lands, and then solve the most important mystery for humanity of the thirteen Inhabitations, to find out how and why centers of civilization arose in the vicinity of the Old Sun. But this is a very difficult task when old and new enemies are on the heels, and the ominous shadow of a pirate captain is inseparable from his ship. For the first time in Russian!
