To Summon Nightmares by J. K. Pendragon in one sentence: (mostly secular) bi Jewish trans man vs. his new gentile boyfriend’s Scary Past with the Occult.
I don’t read a whole lot of horror/paranormal/urban fantasy, so as an outsider there I can speak to the clear and easy to follow worldbuilding of this book’s magic systems, government entities, etc. In other words, if you’re here for the Jewishness or the written-from-a-trans-author transness, don’t be scared off by the whole ‘summoning demons’ and ‘government conspiracy’ angles. And if you’re here for that, well, I think you’ll find it well constructed!
Warning for violence, minor character deaths, self-harm/dysphoria, and some random microaggressions/misgendering.
