Dune is split up into 3 “books”. I told my wife I was getting to the end of book 1 but still didn’t know what was going on, or who these people are, or why I should care. She said she remembered reading Dune once upon a time and couldn’t get into it, and suggested I stop reading it. So I did.
JEDIT: War and Peace is such more interesting, coming back to it after the confusing snoozefest that was Dune.
