I've read the first one, but not the second one. I thought the first story was really cool, as I've not read anything about the Genestealer Cult before, so that was a new experience for me. Glad the Genies are finally getting some time in the spotlight
EDIT: Read the second short story. Felt like someone translated the beginning of a horror film into written form. That's really cool! The forces of chaos are beginning to surface!
