Is peace possible between Light and darkness – and under what conditions? Night is an unusual country, its inhabitants know: the Night Guardian, who created their world, is real. Blind faith is not required here, anyone can turn to the Night and get an answer to their question, and retribution for wrongdoing occurs immediately and inevitably. And at the hand of the Night, everyone is equal: a simple farmer, a foreign emigrant, and the powerful duchess Lady Jane, powerless to break the laws she established, certified by the Night itself. The ambassador of a neighboring country, Commander Peter Craig, is coming here for peace talks. The next day and a half will change the history of the two countries and the life of the ambassador himself.
