Tono-Bungay [EPUB ebook] 

According to Wikipedia: 'Tono-Bungay (1909), by H. G. Wells, is a realist semi-autobiographical novel. It is narrated by George Ponderevo, a science student who is drafted in to help with the promotion of Tono-Bungay, a harmful stimulant disguised as a miraculous cure-all, the creation of his ambitious uncle Edward. The quack remedy Tono-Bungay seems to have been based upon the patent medicines Carter’s Little Liver Pills and Dr. Williams’ Pink Pills for Pale People, marketed by John Morgan Richards. As the tonic prospers, George experiences a swift rise in social status, elevating him to riches and opportunities that he had never imagined, nor indeed desired.
