I do have new books, but one -- Not A Tame Lion, by, um, I forgot -- bored me to sleep. (It's an okay book, actually, but the frequent references to Aslan as the Lion of Judah kind of annoys me. Lewis already said that Aslan is not strictly Jesus reverse-personified and that Narnia wasn't meant to be an allegory, as allegory is scholarly defined. Any Lewis scholar ought to know that and respect that and not use the book for their own purposes.) The other -- a compilation of C. S Lewis' letters -- is too heavy to carry around.
So. I brought The Fellowship of the Ring to work.
Tolkien's foreword always makes me laugh. He wrote, "Some who have read the book, or at any rate have reviewed it, have found it boring, absurd, or contemptible, and I have no cause to complain, since I have similar opinions of their works..."
People do have different tastes. If I had my way, I would make everyone see why I love Lord of the Rings and The Chronicles of Narnia so much until they start loving them too. But then I would have to explain and explain and end up writing something like Not A Tame Lion. And even then, I'm quite certain that I still wouldn't accomplish my goal.
People's likes and dislikes are governed to a great extent by the experiences they have been through, by the type of intellect they have (let me stress, "type," not level), and by the stage of life that they are in. C. S. Lewis once dedicated a Narnia book -- I think LWW -- to a girl named Lucy, for when she would be old enough to appreciate fairy tales again. (That must mean I am either very young or very old!)
Liking a particular author would depend, too, on whether one appreciates the range of the author's imagination and style. For example, I used to really like John Grisham's books, but I eventually felt that his cynical, world-weary storytelling was getting old. Dan Brown's books are truly exciting, but once you've read a couple, you don't need to be Nancy Drew to figure out that the least likely character to be a villain is the villain. On the flip side of the coin, Dick Francis' understated, very British manner of writing, of which I approve, would surely be found boring by many.
To each his own literary preference, then, and may the world never run out of our kind of storytellers.
