I finished False Gods (Horus Heresy, book 2), and here are my thoughts...

I've been reading 40k books, watching the vids, reading this sub for a few years. I was well aware of premise.

Firstly, I loved the book. I listened to it in audible and the voices were excellent. I felt genuinely sad at the betrayal & slaughter of the brotherhood (Auretian Technocracy) for the sake of their technology, and the killing of those speaking out about the Sons of Horus carelessly killing innocent crew members as they tried to save Horus.

That said, my expectation (mostly from reading this sub) was that there felt like a justifiable reason for Horus turning. The Emperor (holy is his name), kept secrets from him, planned to put him and his ilk in the bin and have n00b mortals as the ruling body, etc.

While I appreciate the motivations may be fleshed out more in future HH books, I was surprised/baffled at how quick Horus's turn to Chaos was, and how weak his justifications were. He seemed to go into a warp dream for a bit, talk to sneaky Erebus and then come out full bad guy lol.

Given there's a heck ton of books, I wasn't expecting Horus to pull this turncoat bullsh1t so quickly. Still, onto book 3!
