Status Updates From Dune: The Machine Crusade

So far, hhmmmm, if you've read the original Dune series, you've heard about the machines taking over for thousands of years, but that's about it.
This is the 2nd book in the series that Brian Herbert wrote from his father's notes to explain what exactly happened. In it, you'll find the beginning of many different groups and fights, but I'm not going to be able to spoil any in around 100+ characters.
