It's a scholarly work on the development of The Hobbit manuscript, and since the Hobbit is my favorite Tolkien work I was uber excited. Seriously, this is like putting a delicious dinner for my brain right in front of me.
Anyways, I opened it and read a few pages. Of all the interesting things, the one that stuck out was actually a little tidbit about C.S. Lewis. As we all know, C.S. Lewis and Tolkien were good friends and they would read each others works. Upon hearing about this new book Tolkien was working on, Lewis requested to see the early draft of it. And then...he accidentally destroyed it! Twice! I mean, I don't know what's worse, the fact that Lewis was so careless twice, or the fact that Tolkien was stupid enough to give it to him the second time! My goodness!
I guess the moral of this story is, if the ghost of C.S. Lewis comes and wants to see the draft of your potential master work, don't give it to him.
