I read the Cawl book, and it has some events that could be a Big Deal if they’re pursued further.
Same with Josh Reynolds’ Apocalypse, and Dark Imperium: Plague War. Aside from these I’m a little (a lot) behind 40K novels because my main focus is Heresy era. There, I just finished The First Wall, and I’m three Primarchs novels (and Valdor now) shy of being 100% caught up. Unless you count the FW books...
