Hey!
I just purchased a book on Google Play Books, and realized that I couldnt put it on my kindle. I then found out that you can easily convert the ACSM file provided by Google into an EPUB file. The problem is that you need a Windows or a Mac to run Adobe Digital Editions.
Therefore I will pay anyone $1 who can follow these steps:
http://www.epubor.com/convert-acsm-to-epub.html to convert it to EPUB and remove the DRM.
PM me if you are interested and ill send you the ACSM. You send the epub first. Can provide proof of purchase of book if you want.
