Somno Slave

Somno Slave is not messing around, y’all — Deogal tells you flat out in the blurb he’s not interested in her consent, he’s interested in her collapse, and then the book fully commits to that bit. This is criminal x psychologist with a supernatural twist: Rheda thinks she’s studying a mute murder suspect from behind glass, but by night he’s inside her dreams, rewriting her from the inside out. Non-con and dub-con hit hard here, somnophilia is basically the whole premise, and more than one reader called it erotic horror wearing dark romance’s clothes — don’t expect a soft landing, this is a duology and that cliffhanger is described as brutal. A reported 25 ARC readers DNF’d it, so this is eyes-open, triggers-checked territory. But if you live for unrepentant villains, zero redemption arcs, and psychological warfare disguised as seduction, Deogal might just become your next problematic favorite.

Book Description

I am not interested in her consent.
I am here for her collapse.

Doctor Rheda Ainsley enters my cell believing she has been trained to observe, to diagnose and sentence me to death. But she doesn’t know that I am not here to be analysed. I am here to overwrite her. To hollow her out and rebuild her memories around my seductive whispers.

When she closes her eyes at night, it’s my face she fantasies about. It’s my hot body touching her unconscious one.

I correct her thoughts in her sleep. I teach her how easily control dissolves. I isolate her from her profession, her colleagues, her sense of moral authority. I break her until she needs me to function. Until she craves the place where I hurt her because it is the only place she feels whole. Until there is no version of her left that can exist without my presence pressing against the inside of her skull.

This is not seduction.
This is conditioning.

Dream by dream, I will make my sweet little doctor my Somno Slave.

Author note: READ WITH CAUTION. This is an incredibly dark romance novel that includes scenes some readers may find disturbing. Please ALWAYS check the trigger warnings on my website, and of course, reach out if you would like to confirm whether any triggers are present inside the story.

Content Warnings

This one's a heavy hitter. The core premise is non-con/dub-con — the MMC (a sleep paralysis demon) explicitly states he isn't interested in the FMC's consent and enters her dreams to control her body and mind, so somnophilia is baked into the entire plot, not an incidental scene. Expect sustained psychological manipulation and gaslighting as he isolates her from her job, colleagues, and sense of reality, plus toxic/possessive dynamics and what several readers describe as Stockholm-syndrome-esque attachment ("she craves the place where he hurts her because it's the only place she feels whole"). The MMC is a convicted serial killer/murderer on death row, and there's an on-page torture/physical-assault scene where another character (not the FMC) uses "painful methods" to interrogate him — one reviewer said it was hard to watch. Expect general violence and some gore, plus heavy themes of mental unraveling, trauma, and loss of grip on reality for the FMC. One reviewer also noted he deliberately deprives her of sleep as a control tactic (not on the master list, flagged below). No HEA — it ends on a cliffhanger as part of a duology.
