I was able to open it on Calibre 7.6.0+ds-1build1 on my Mint Linux laptop.
I was trying to read it on the default document reader in my Mint Linux install. It would open the file and show the chaperts, but as soon as I tried to click on a chapter it closed.
It does work with Calibre, but not on my Android phone. I'm really hoping I can figure out how to make it readable on my phone so I can read it on the go.
