Children of Dune

Children of Dune is where Herbert goes full mythological, and it works.

The twins Leto and Ghanima are carrying the memories of every ancestor they've ever had — that's a wild premise and Herbert uses it to dig even deeper into the questions the series has been asking since book one. What is humanity? What does it mean to choose your own path when you can see every possible future? Leto II's arc in this book is one of the most ambitious things I've read in sci-fi — the choice he makes and what it means for the universe is staggering in scope.

This one is dense. There's a lot going on between the political machinations, the internal philosophical debates, and the mythology Herbert keeps layering on. It rewards your attention though. By the time you get to the ending you realize the trilogy has been building toward something genuinely profound and not just a fun space adventure.

I loved this trilogy. All three books are doing something different and they all earn it. Herbert built something that doesn't really have a comparable in the genre. If you haven't read it, clear your schedule.
