Are you a lover of Audio Books?
Some books are really well suited to audio and Shadow Over Edmund Street is one such book. It's now available in multiple formats (CD, MP3 and retail 3rd party suppliers - Audible, Bookbeat, Storytel and Findaway and Apple).
And the CD version is available in community libraries worldwide, in borrowable format (if you can't find it at your library, ask them to get it). :-)
