I'd recommend 'Ciaphas Cain: For the Emperor'. It has elements of horror but also a lot of humor, which makes it easier for beginners to get into the Warhammer 40k horror genre. The character of Ciaphas Cain is really interesting.
'Genestealer' is also quite well - known. It focuses on the terrifying Genestealers and their insidious infiltration. The idea of these alien creatures slowly taking over and the horror they bring to the Imperium makes for a very engaging horror novel in the Warhammer 40k setting.
The idea of chaos corruption is terrifying. A character can start off normal, but as they are exposed to the taint of chaos, they gradually change. Their appearance might distort, and their mind becomes filled with dark thoughts. It can happen slowly and insidiously, like a disease that you can't see until it's too late. For example, a simple Guardsman might start having nightmares, then find himself drawn to strange symbols, and before he knows it, he's a servant of chaos. And this can spread like wildfire in a military unit or a civilian population.

Another is 'Gaunt's Ghosts' series, which follows the Tanith First and Only regiment through their various battles and trials in the grim darkness of the 40k universe.
