"Sue Burke, author of Semiosis and Interference, gives readers a new near-future, hard SF novel. Immunity Index blends Orphan Black with Contagion in a terrifying outbreak scenario. In a US facing growing food shortages, stark inequality, and a growing fascist government, three perfectly normal young women are about to find out that they share a great deal in common. Their creator, the gifted geneticist Peng, made them that way--before such things were outlawed. Rumors of a virus make their way through an unprotected population on the verge of rebellion, only to have it turn deadly. As the women fight to stay alive and help, Peng races to find a cure-- and the cover up behind the virus"-- Provided by publisher.
