This book is a wayyy different breed than the first 3 books of the dune series and it was a lot harder to get into than the first half of the series. I fully would've rated this 2 stars if it weren't for how visceral and satisfying the ending was. 

For every good scene in this book, there's 5 scenes talking about whether or not Leto's grotesque wormy body can have sex, why the military encourages latent homosexuality, the usage of people as breeding studs, nonsexual acts being described as causing orgasms, and just straight up lesbophobia. It's a lot to slog through.
