A novel about split personality, the components of the self and genetic engineering. It tells the fate of Joanna May, who at the age of 60 discovers that she has been cloned and there are in fact four other versions of herself in existence.

Joanna May thinks herself unique, indivisable -- until one day, she discovers there are five of her. How will the clones withstand the shock of first meeting each other, and will Carl, the clones' creator, take revenge for his Joanna’s infidelity and destroy the sisters one by one?
