The search, which lasted almost five hundred years, is over. Mark Gomaro returns home, and Tim and Inga have yet to find out where their real home is. And this is difficult, because once you come to the attention of the special services, you will remain there forever. Will the fact that they were involved in another secret operation help or hinder the heroes? Did they involve you... Or did they volunteer themselves? Because there are things that cannot be left unfinished: the Admiralty of Tellurium and the Mars Safety Committee, mercenaries from Danteus and unknown strangers, new friends and old problems... What will Tim remember when he gets to Mars? What will Inge find when he returns to Nova 17? And will Matveev know where the wild quails are?..
