Agreeing to deliver an archaeological expedition to a remote system, a free pilot with the call sign “Pop” expected easy money. It would seem that what could be simpler - pick up people and equipment, unload them near the ancient ruins of a lost civilization and return back? However, as happens in life, all plans went awry and it was by no means his fault. By absolutely coincidence, this contract came at precisely the moment when a race hitherto unknown to people decided to test the strength of the boundaries of the space inhabited by humanity. A new crew, exploration of the ancient ruins of a forgotten civilization, large-scale space battles between human fleets and Alien armadas - all this in the final, fifth book of the “Pilot’s Notes” series.
