I discovered this book on my Libby app while browsing the library for something to read. It is a great book for those interested in the history of science fiction, or even just history in general. It includes the stories of those mainly responsible for sf's rise to popularity in our culture (Campbell, Asimov, Heinlein, and Hubbard--all fascinating characters). Throw in a helping of that crazy dianetics stuff and you're in for one absorbing ride.
Many thanks go to its fine author: Alec Nevala-Lee.
