Charlotte Kerner's book "Blueprint" addresses a highly topical issue: human cloning. The story centers on the talented composer Iris, who suffers from an incurable disease. To preserve her musical gift, she decides to be cloned. This creates the unusual situation for mother and child: genetically identical monozygotic twins. The daughter, Siri, bears the heavy burden of this legacy and lives as a carbon copy of her mother. This confronts her with challenging questions about identity and individuality. Where are the boundaries between her own personality and that of her mother? How does one find their own "self" in the shadow of another? Only after her mother's death does Siri succeed in discovering herself and finding her own path.
