If young people have a natural craving for the sacramental, that craving may be awakened and sharpened by such books, and the reader led to look for more. I hear certain pop songs and am instantly brought back to the particular year when the song was most popular; how much more is a book series nostalgically wound up with one’s life if one reads it over years, seeing the characters handle the difficulties of school and first crushes while you are, and yet… their lives are exciting while yours is rather dull. On the other hand, perhaps the craving is simply sated by the wrong sort of food, and the youth are led further astray because the pseudo-sacramentality of Harry Potter tastes enough like the real thing to make the reader stop there.
