A compelling novel based on the high-stakes biotech industry and the science behind Viagra from the internationally known Father of the Pill. The fourth installment of Carl Djerassi’s pioneering science-in-fiction tetralogy tells the story of a husband and wife team who devise new solutions to problems associated with sex and reproduction. Renu Krishnan is an Indian-born, American-educated scientist who discovers how NO (nitric oxide) can help men with erectile dysfunction—the scientific rationale behind Viagra. At the same time, her husband, Israeli scientist Jephtah Cohn, develops a new approach to ovulation prediction, which is also based on factual research. When Wall street gets wind of their discoveries, the couple catapults in the fast paced world of lawyers and IPOs, where scientists are now a hot commodity. Deftly exploring the demanding worlds of academia and high finance, Djerassi brings back many characters from his three earlier novels for a satisfying conclusion. | No by Carl Djerassi, Paperback | Indigo Chapters
