I just bought the Kindle version of SOTW Volume 1 through the WTM website and I must be missing something because I can't figure out how to actually get it on our Kindles. Right now the only thing I've been able to do is read it to one kindle at a time by going to my account on WTM and downloading it. But every time it gets closed, it's gone from the Kindle. It doesn't show up anywhere, not even in the downloads area. Will I be able to add this book to my Amazon account somehow so that it is accessible to both my children on their Kindles? If anyone can help it would be greatly appreciated!
