I did it! I have Kindle on my new tablet.
Actually two younger, smarter, naturally tech-wired people did it. Katie, a garden co-worker, set it up. Monica, my daughter, activated it and downloaded a novella by fellow RWA Scriptscene member, Pepper Phillips, called Unconditionally.
I've been shown how to play with the background color, and contrast, but I think I'll leave the settings as they are, for now.
It will take some repetitious to get comfortable with this device. But I'll be able to read romances that have been inaccessible. And I'l get comfortable with e-books, just in case I elect to self-publish my WIP.
I've joined the 21st century.
