			Thanks for the heads up eschwartz.  I have since moved my Calibre library out of my Google Drive folder.  I now just "save to disk" my pdf books to this folder and sync with my Good Reader app over wifi.  I then use Calibre to hardwire/usb sync my epub books to my Marvin app.  I am now patiently waiting for one of these apps to support both epub and pdf.
