I'm a voracious reader and still, I suck as a literary prophet but I suspect that Paulo Coehlo's works, The Alchemist and Eleven Minutes for instance, are very inspiring and influential, and will not be brushed off by history. Perhaps we'll look on him as a great classic writer. Perhaps not. His novels have the themes and motifs of classic books. Name a few books in the last 20 years and indicate the reasons without spoiling the plot.
