I came across this and thought some of you language enthusiasts may enjoy it for your middle to upper graders, as well as yourselves. It also touches on why the english language was so important regarding the Bible's ability to be translated into English so so many could read it for themselves.
It's called "King ALfred's English: A History of the Language we speak and why we should be glad we do."
I haven't read it, but am interested; but I trust the website where I found it in their types of books they sell.

The site says it's for ages 10-15.
