Katia - After I read you post about your grandson reading so fast, I thought of my 11 year old grandson who is the same way. If you grandson had an ebook that could download library books and a library card, it would save a lot of money. I may think on that for a while for my grandson. Most librarys have the ebooks capability and their websites list the compatible devices. I know the Nook is, don't think the Kindle is, but I know that there are others that are compatible. Just a thought. The nice thing is that you don't have to waste gas to go to the library, and the books go back though cyber space when the loan period is up. audo books can be gotten also.
