This is a collection of covers for books published relatively recently by authors John Robert Colombo and Ruth Colombo. (In the case of the Sax Rohmer’s Sumuru, JRC contributed the foreword.)
The covers were designed by Bill Andersen, in collaboration with the authors. The music bed is sampled from this album, if you wish to purchase it online. John Robert Colombo has an extensive list of titles now available as Kindle ebooks.
