Welcome to MR, Catherine!
I know I said, "Hi", already, but this is the official welcome.
It's very generous of you to put your book up for free on
feedbooks and
smashwords. We are a worldwide forum of many devices and really appreciate authors who take that into consideration. (We especially like no DRM and NO geographic restrictions.. free, too
).
Thank you and have fun exploring the forums. Just ask if you want to know anything.
