The Depth is the center of the Sector, its dark, dangerous Heart. The Depth brought Danila Astrakhan and his companions to a strange place. In this place, physical laws are distorted, bloodthirsty creatures and even more bloodthirsty people live here... or not people? What is this - a military testing ground, another world, a new Sector, or something completely different? And what is this LOOK that the heroes constantly feel here? Someone - or something! - is watching them... A mysterious hostile OWNER who does not want to reveal the incredible secret of these amazing territories to strangers.
