Your MS Book Shop is here. You should be able to find many books, by, about, and for people with MS. We have several in our library - meaning hardback and paperback. However, we also have many on our Kindles, which are only in ebook format.
There are pros and cons with both. I love physical books. There's just something about holding a new or lovingly read book in your hands and seeing the words on the pages. The ebook, though brings a whole other dimension to reading, from adjustable sized text, to reading out loud, although the voice is a little stilted.
Either way, I couldn't fathom getting rid of either. So I will keep them both. In the meanwhile, here is a list of ebooks which may appeal to you. Enjoy!
