Marionella 'Gulya' Koroleva was a Soviet child film actress who volunteered as a medic in the Second World War and was killed in November 1942, aged twenty, near Stalingrad. By the account the book popularized, she carried dozens of wounded men off an embattled hill under fire, then took up weapons and joined the assault before being killed. She left behind an infant son, and her real death was turned into a model life for Soviet schoolchildren.
The book arranges a biography as a series of 'heights', trials of increasing difficulty that the subject must overcome in turn. Each one conquered in youth, whether physical, personal or moral, rehearses the will needed for the next. The final height, a literal battlefield hill, is presented as the logical summit of all the earlier ones rather than a sudden act.
The book argues that wartime courage is not spontaneous but built up in small peacetime habits, such as finishing hard tasks, refusing to quit and taking responsibility for others. The heroic act is therefore offered as something within reach of any young reader who practices those habits now. This turns a death into a behavioral instruction for children.
