Hello Fledchen. Welcome to MobileRead. In addition to the government services for the blind, the publishers at Baen books will entitle you all their SF and Fantasy books. See
https://www.webscription.net/news.aspx?showarticle=2 for information on how to apply for this service.
Although I have no problems with print books, I found that trying to read books on my computer was a significant challenge, so I'm enjoying the dedicated readers that I have purchased.
We hope you hang around here at MobileRead and tell us all about the books you like -- and even those you don't. There are thousands of eBooks available in the library here at MobileRead. And, while those same titles are available elsewhere, in most cases you'll find that the ones uploaded here are much higher quality.
