The book contains two historical stories. The story "I do not renounce!" tells about a difficult time when Russia fell under the blows of the Mongol-Tatars. Prince Mikhail Vsevolodovich Chernigovsky and boyar Fedor were martyred in the Golden Horde, but did not betray their native land, did not abandon their Orthodox faith. A tale of fortitude and betrayal, of true popular memory and oblivion.
