The eponymous twin teenage sisters from middle class backgrounds, Kara and Ira, are on the run from the authorities. They have joined a Partisan group based in the Balkan mountains. The Partisans are a mixed bunch of young and old communists and Peasant party members, all dedicated fighters against the Bulgarian monarchist regime and their German allies. Many have adopted colourful nicknames and Commander Medvev, who is a former refugee, speaks Bulgarian with a heavy Russian accent. From the start, the pretty twins seed confusion in the hearts of the fighters. Only a few hours into their adventure, the rebels are attacked by government forces, led by the fearsome captain Night. The few survivors find safety in the Forbidden Wood. Lost in the mountains on the border between Bulgaria and Serbia, the twin sisters Kara and Ira are left to the mercy of the elements and separated. The Cold War finds the Twins on the opposing sides of the Iron Curtain.  A two episodes story. Although the second novel can be read on its own as a separate piece, the two parts together form a kind of a saga encompassing the period between 1943 and 1953 and an ironic gaze on one of the most dramatic episodes in European history: the Partisan movement and the communist propaganda.
