Thanatonauts. The Empire of Angels

Death. A point of no return that makes the living feel bewilderment and fear. No one has ever returned from there, and no one has yet been a guest beyond the edge of life. However, with the invention of thanatonautics, everything changes. The daring Michel Penson and Raoul Razorbak have invented a way to travel along the edge of shadows, leading to unpredictable consequences – for each confession desires to prove its correctness and to colonize the afterlife.
Michel and Raoul will have to practically understand all the subtleties of the angelic craft and figure out the murky heavenly hierarchy. But they would not be true explorers if they stopped there. Where do angels go after fulfilling their purpose? Who makes decisions beyond the angelic realm? And what if the answers to these questions lie in other galaxies?
