WH40k reading update!
Chewed through both of the Watchers of the Throne novels (The Emperor's Legion and The Regent's Shadow) in quick succession. Fun reads, both of them, and pretty quick. I feel like in both of them, the third perspective (the Chancellor of the Imperial Senate, though the role changes hands between books) was a little underbaked - most of what I found interesting in the second was how that character had a very different perspective on her relationship with the first than he did in his segments in the first book. In theory, a more political maneuvering focused perspective on events is very cool, but in both cases they're just hugely outmatched by the system in front of them and don't really accomplish much. There's some narrative value to that, I suppose, but it doesn't make for a very satisfying read. They do still offer a very different perspective on events to almost all other 40k characters, though, who tend to be either helpless civilians or some flavor of physical/psychic badass, so I'm definitely still glad they were included.
Of the other two perspectives, I found myself really enjoying Aleya (the Sister of Silence)'s view on things. She's cynical and not afraid to mouth off (so to speak), which is a rare attribute in 40k characters, outside of Cain. There was one disconcerting moment with her where she just sorta... mind-blasts a member of the Palace waitstaff for no good reason? Like, sure, it's 40k, almost nobody here is a good person, but that's no cause to be cruel to the waiter (so to speak). I really like her, otherwise, but it's a hard thing for me to move past for some reason. Valerian (the Custode) was decent as well, but honestly it was pretty clear that he was mostly there for some exposition on the Custodians and to facilitate the bolter guardian spear porn.
Still, despite my issues, they're both very good books by 40k standards. Solid prose, decent plotting and character writing, and on net a lot of fun commentary about the Imperium and the setting, if that's your thing. Gotta embrace the unreliable narrator for some of it (the first Chancellor going "actually, the High Lords really are the best people to be leading the Imperium and we should be glad they're here, and also it's good that we get massive privileges even while so many starve" comes to mind), but it's still fun getting stuff like Valerian musing on how things wouldn't be going half as badly if the High Lords put a tenth of the money they spend on cathedrals into building and filling granaries. Very big picture thinking from a golden banana.
After that, read some Siege of Terra stuff. I fell off the Horus Heresy a WAYS back, so some of the events being referenced are lost on me, but they mostly do an okay job of filling in the gaps through context. Got through Solar War and The Lost and the Damned quite quickly. Found the writing much better in the first than the second, but both have a lot to recommend them. Solar War is mostly a 40k naval combat thing, and while John French is not David Weber (or whoever your favorite space opera combat guy is, if you're not as fond as I am of ships firing missile counts that have to be expressed in power notation), there's still some cool scenes and fun twists. The way the novel ends makes it all feel kinda pointless, but I suppose that having the traitors keep the upper hand throughout the preliminaries was to be expected. Still don't like Abaddon much, though.
The Lost and the Damned takes a hit on the prose front, but does move to ground combat, which Guy Haley is pretty good at. Takes a little while to get rolling, but once it does it goes by very quickly. I liked Katsuhiro a lot here. Unlike Solar War, the Primarchs were a big focus here, so we got some cool stuff with the Khan, Sanguinius being mopey, Dorn being Dornish, and Malcador being weirdly casual with all of them. I loved the stuff with the Night Lords fighting the Blood Angels for control of the wall and Kharn trying to contain Angron (and himself).
Currently kinda stuck on The First Wall, which I am just not enjoying much. A lot of 40k combat has this problem where only one side is allowed to be good at their jobs at a time - it's what makes most bolter porn so dreadfully predictable. Halfway in, and Gav Thorpe is not doing a good job of preventing this issue from rearing its head. We get a whole chapter of the Imperial Fists effortlessly dismantling a traitor advance, and then a slew of chapters from the traitor's perspective where the Fists seem completely incapable of mustering a response to their advance, then back to the Fists crushing heretics, then back to the heretics crushing Imperials... nobody hits significant resistance, somehow. The plotlines are getting real muddy, too. Mostly at this point I just wanna push through it to get to Saturnine, which I've heard really good things about.
