Classics share certain characteristics that attract readers from generation to generation including memorable protagonists with vivid, distinct personalities and strong points of view about the world around them; an exploration of the human experience that expresses a universal truth about how humans perceive the world around them; a richness that rewards multiple readings; and an timelessness that finds modern audiences regardless of the period of time in which it was originally written.
