Seemingly it's not too distant future, but so much has changed… Only people stayed the same.

Seraphim — (the main character) works in a modest firm. It sends people's letters to their dead relatives. Some do it because they feel guilty, some just miss their relatives, and others send letters to say what they've been meaning to for a long time. The messages are delivered by messengers of the horizon — suiciders who have nothing left to do but die. Some do it in exchange for a fancy funeral, others to give their family a happy life. Nothing foretold upcoming changes in Seraphim's life but something inside him clicked. His outlook on life changed and he saw it in a new light…
