It has taken me 37 years to write this biography of author Robert W. Chambers. Along the way, I wrote and published many articles about him, but did not complete the biography until 2014. I got the idea of writing it when I was 15, and the reason I got the idea is the same reason it has taken so long to write the book. There simply is not that much information about Chambers out there. Despite his fame and thorough integration in New York high society, very little was written about him during his lifetime. This volume contains the Expanded Edition of the biography, Robert W. Chambers: Maker of Moons, as well as the collection of articles, originally titled, Robert W. Chambers: In Search of the Unknown Author of The King in Yellow.
