John Senior, in the appendix of his book The Death of Christian Culture, provides a large list of "good" books. He argues that in order to read the "great" books of Plato, Aristotle, St. Augustine and St. Thomas, we need to "replenish the cultural soil that has been depleted" and create a place where those works can thrive by cultivating "an imaginative ground saturated with fables, fairy tales, stories, rhymes and adventures: the thousand books of Grimm, Anderson, Stevenson, Dickens, Scott, Dumas and the rest."
Take a look at Senior's list (and the rest of the book is well worth reading). [Amazon.com allows one to view most of the list through its "Look Inside" function]
Update: You can now find the book list in its entirety here.
