"Stuart Ressler, a brilliant young molecular biologist, sets out in 1957 to crack the genetic code. His efforts are sidetracked by other, more intractable codes—social, moral, musical, spiritual--and he falls in love with a member of his research team. Years later, another young man and woman team up to investigate a different scientific mystery: Why did the eminently promising Ressler suddenly disappear from the world of science? Strand by strand, these two love stories twist about each other in a double helix of desire. The critically acclaimed third novel from Pulitzer Prize-winning author Richard Powers, The Gold Bug Variations is an intellectual tour-de-force that probes the meaning of love, science, music, and art.
