When I retired in 2008 after carrying a cell phone for years on standby for our control centre I swore I would never get another cell phone.

I was wrong.

It took ten years but I finally broke down and got a SpeakOut pay-as-you-go FiGO Ultra. It's got everything I was looking for except for one small thing. It didn't come with an e-book reader. There are a number of free e-book readers available on teh Chrome store but a number of them stream ads. Can anyone suggest a free e-book reader for Android that does not stream ads? The only format it has to support is epub. Fortunately, epub is an open format so this shouldn't be a problem. I can convert any format to epub.
