Dune is a favorite, I marvel at how well-crafted it is each reread. Like the first book, there‘s a mix of philosophy, political and religious commentary, strong character-development (albeit male-centric) that I find engaging. Messiah deepens our knowledge of political forces in interesting ways. Otherworldliness is the landscape and character and the outliers, while seen as freaks within the world, are the most compelling for the reader.
