Description, by Lois Tilton [Locus]: "Setting: an alternate Cold War. Marya heads a secret Soviet cloning lab in which she is employing Lamarckian principles to develop organisms capable of withstanding radiation. She is an obsessive personality, but lately her primary obsession is with her daughter, who died of leukemia. In the course of numerous recreations, she has managed to eliminate Alexia’s cancer, but she still dies every time, after about sixteen days of life. In the meantime, she has to hide Alexia’s illicit presence from Soviet inspectors and hold off commando raids from the evil, Darwinian decadent capitalist regimes which want to destroy her work."
