Controlled Substance

Okay fam, this one is unhinged in the best way. Sable Sinclair dropped us in a psych ward with a heavily sedated psychopath, an oblivious heroine whose “clean, factual” reports are literally the key to his cage, and a MFM why-choose with a bodyguard who keeps finding excuses to walk her to her car. It’s Jekyll & Hyde hero, institutional forced proximity, and full-send morally black MMC — the kind who was waiting for a woman exactly like her. If you’re here for serial killer romance where the villain stays villain and the “who did this to you” energy hits from both men, one-click immediately.

Book Description

Jude Chadwick killed at least twelve men over six years. Left each one staged at their own table with a signature so brutal the FBI gave him a name. The media calls him The Shade. The facility calls him their most dangerous patient. I don’t see what the fuss is about.

I’m the court-appointed behavioural monitor assigned to assess his treatment at Greenridge Forensic Psychiatric Facility. My job is to observe, document, and report. That’s it. I’m not his therapist. I’m not his friend. I’m the independent set of eyes making sure the system isn’t abusing a patient’s rights — no matter what that patient has done.

And the system is definitely abusing his rights.

The sedation doses don’t match what’s on file. The restraint protocols are excessive for a man who sits across from me and asks about my day. Staff are terrified of him. I’m not. I don’t know why everyone keeps telling me I should be.

My reports are clean, factual, and damning. Every one I file chips away at the facility’s case for keeping him heavily sedated. His lawyer is using them to build a legal challenge. The head of security keeps finding reasons to walk me to my car. And the quiet patient in Ward A has started learning my schedule.

I thought I was protecting a man’s rights.

I didn’t know I was the key to his cage. And he’s been waiting for someone exactly like me to turn it.

Content Warnings

Go in knowing this is set inside a psychiatric facility with a heavily sedated, morally black serial-killer MMC, so expect captivity/imprisonment, drugging, medical trauma, and heavy institutional power dynamics throughout. There's on-page violence and murder tied to the serial killer plot, plus stalking (the MMC learns the FMC's schedule from inside Ward A), obsessive/possessive behaviour, coercion, and psychological manipulation/gaslighting from a Jekyll & Hyde hero. Expect dub-con energy given the power imbalance and psychopath hero, sharing dynamics between the two MMCs (MFM why choose), plus emotional and mental abuse woven into the institutional setting. Toxic relationship dynamics and trauma/PTSD are baked in. Verify against on-page content and reader reviews before locking triggers — reviewers often flag extras like specific SA, gore, or on-page torture that aren't obvious from the blurb.
