The Peripheral

Release: May 2026 | Genre: Psychological Thriller

After a flash burn on the job, welder named Jake begins seeing shadows flicker at the edges of his vision. At first, he blames the injury, until the shadows reach for him. What follows afterward forces Jake to confront a buried secret he’s spent years trying to conceal.


The Void Protocol

Release: June 2026 | Genre: Psychological Crime Thriller

Investigative journalist Paul Chandranand, still haunted by the success of The Wolcott Murders, is ordered back to the ADMAX facility to face serial killer Jasper Wolcott once more. Armed with Detective Thorne’s case notes, Paul retraces all 37 murders, documenting each crime scene as Jasper reveals the methods behind his madness. What emerges is a meta‑narrative—A Serial Killer’s Guide to Stain Removal and Other Life Hacks—that pulls Paul into a psychological unraveling he never saw coming.


The Chaos Particle

Release: August 2026 | Genre: Metaphysical Psychological Thriller

Disgraced detective turned private investigator Heath Miller is working a routine cheating‑spouse case when he finds his mark comatose in a park, seated upright in the lotus pose. His curiosity deepens as more meditators are discovered as hollow husks, leading him to the only survivor—Vikram Kamalpan—whose incoherent ramblings offer no answers. Desperate, Miller tries meditation himself and encounters Sean Gladstone, a man using the minds of others to reach the Chaos Particle in a misguided attempt to rewrite his past. Three men are set on a collision course that will expose the truth binding them together.


The Scar City

Release: November 2026 | Genre: Dystopian Psychological Thriller

After a global catastrophe, Copernicus Graves, one of seven leaders rebuilding their fractured nations, sets out to resurrect a unified America built on order, uniformity, and a collective purpose. His vision falters when a rebel faction challenges his doctrine, insisting on individuality over compliance. As tensions escalate across the quadrants, Graves must confront the cost of enforcing utopia on a world that no longer agrees on what it means to be human.
