The son of the last Tsar Nicholas II, Tsarevich Alexei, lived only fourteen years. He witnessed the decline of a great empire - the Russian Empire, which he was supposed to inherit years later. Fate and history, as we know, decreed otherwise: the prince shared the fate of his entire family, who were executed by order of the revolutionary government. The book tells about the life of the heir to the Russian throne and his family circle. The author builds a narrative based on extensive documentary material, without idealizing Russian history. The book is intended for a wide range of readers.
