In this book, Michael Ward makes the rather astonishing claim that he has discovered the "hidden inner meaning" of C. S. Lewis' famous seven-volume sequence, the Chronicles of Narnia. It is reassuring to the reader that Ward sees and states at once the obvious skeptical responses to such a claim. If the "Narniad" has had a hundred million readers, as by now it probably has, what are the odds on the hundred-million-and-first suddenly stumbling on the truth? And if scores of millions of readers have taken delight in the books already—The Lion, the Witch and the Wardrobe was rated by British readers among the ten most popular novels of all time, and that was before the movie came out—would finding its "secret imaginative key" make any difference? Does it need one? And why did Lewis hide it? He has no reputation as a secretive person, or as a poor communicator.
Ward considers all these objections in the course of an argument which is at once subtle and sensible, a combination not often found in modern academic writing.

In any case, the "hidden key" to the "Narniad" is extremely prominent in Lewis' works, both academic and fictional.

These seven heavenly bodies still determine our days of the week (though some unknown mind long ago converted four of them, in the Germanic world, to their counterparts ...
