A fun read! Dark but not dour. It promises the weird and delivers in full.
I'm not familiar with the Pagham universe, but sign me up for occult research, a house seemingly rife with wrongness, a patron with suspicious motives, and plans within plans.
I dislike invoking Lovecraft, but Rosens is able to capture only the best features of his stories. A compelling focal character delving into what humanity was never meant to know, their slow descent and all the horrors that accompany it.
If any of that sounds up your alley, you owe it to yourself to check this out! It's a quick read that you'll savor a long time after.
