As someone who took up Linux in 2002, and stopped using Windows entirely a few years afterward afterward, the strongest recommendation I can make is that this is the only software I ever paid money for. I bought the licence for the premium version for 40 dollars, and I was happy to do it. I haven't used it in a while, but in April 2019, I downloaded it from my Dropbox, and I'm running it from Ubuntu 18.10 using the Windows Emulator WINE. So far, it's running without a snag. I intend to use it to study the Mueller Report.
The version I'm using is the Trial-Pro version. Even though I paid for the password, I lost it, and so after the 30 day Trial version is up, I may need to reinstall WINE.
READPLEASE is easy to use, and without its help, years ago, I may never been able to study those book years ago to learn how to use Linux. (I have an English Degree. computers were not my thing.) The simple interface scrolls through the text, making it easier to follow and comprehend difficult material. It was worth paying for the Premium version all those years ago, but I can report that the free version is useful and effective.
I'm only giving it 8 out of 10 because in 19, there are more natural sounding speech synthesizers. Fifteen years ago, READPLEASE was the only text reading program I could find that wasn't painful to listen to. More
