As new copy in near fine DJ, slight signs of shelfwear. From Flap: "Tony Devlin, a British graduate student at a University in upstate New York is beginning a Doctoral thesis in genetics. Looking through old files to discover what has been done in recombinant DNA, he stumbles upon a series of photographs of himself. Only one of those photos is actually Tony Devlin. The others are similar but different people born at different times with different mothers. Set in the future, the story explores the questions that arise when humans have been secretly cloned, and then find out about themselves."
