Conversion problem from PRC to anything

I picked up a recent free Kindle book on Amazon. (This one to be precise.) I noticed it had an embedded font. I thought I'd try to convert it to a different format to see how that was done and have discovered I'm unable to do so.

I don't believe there are any DRM issues with this file.

I receive the following error from Calibre 0.6.38 when trying to convert to ANY format. Thanks for any advice!

Code:

PRC is a generic extension that can be a number of different formats. Most of the time it is MOBI. However, in the case of Kindle4PC it uses .prc for all books. This book is in the Topaz format which calibre does not support.

Well, that explains that, then. Thanks!
