Two conjoined Russian twins, Masha and Dasha Krivoshlyapova, face a bleak future in a Soviet system that views them as scientific curiosities and societal outcasts. Despite predictions of early death and the constant threat of institutionalization, Masha's fierce determination to survive clashes with Dasha's fearful nature, creating a complex dynamic as they navigate a world that seeks to define them by their unique physical connection.

The novel has been praised for its compelling narrative and exploration of survival against immense odds, with one review calling it a 'wonderful book'. The story's focus on the resilience of the human spirit, particularly through the lens of the Krivoshlyapova twins, suggests a powerful examination of identity and connection. The historical backdrop of Soviet Russia provides a stark contrast to the intimate struggles of the protagonists, likely creating a rich and layered reading experience. The narrative's progression through significant political shifts implies a deep dive into how external societal changes impact personal lives and relationships.
