You don’t normally read 40k for dense, allusive prose that carry echoes of some of the great prose stylists of the 20th century, but with Peter Fehervari’s 40k work this is exactly what you get. The Reverie is a fascinating take on the grim dark of the far future, one that repays lingering over the words as well as paying attention to the plot (in fact, I lingered so long over the words that I got a little lost in what was actually happening). It’s as close to a philosophical 40k novel as has been written, a novel-length investigation into the corruption that turns to canker all the best intentions of even the best characters within this universe. So if your preference in 40k skews towards creeping dread and the long, slow dissolution of the few citadels of hope in that universe rather than bolter porn, then this is the story for you.
