Some doors should never be opened.
When trauma nurse Marisol Vega receives an invitation to participate in a mysterious overnight psychological study inside the long-abandoned Saint Dymphna Psychiatric Hospital, she expects a scam. Fire investigator Gabriel Navarro, paramedic Jamal Brooks, and social worker Monica Reed receive the same invitation-and the same promise of $10,000 for one night.
By morning, every exit has vanished.
The hospital transforms into an impossible labyrinth of pristine white corridors, where each participant discovers a door bearing their own name. Behind every door waits the one person they have lost, the one mistake they cannot forgive, or the one memory they would give anything to relive.
The Mercy Rooms never force anyone inside.
They simply offer exactly what each person wants most.
As reality fractures and one participant after another disappears into their assigned room, the survivors uncover a terrifying truth hidden beneath the hospital-an ancient force that doesn't hunt with claws or weapons, but with hope itself. To survive, they must reject the lives they've always wished they could have and choose the painful truth over perfect illusion.
But every refusal weakens the last barrier keeping something far worse imprisoned beneath Saint Dymphna.
Dark, atmospheric, and relentlessly suspenseful, The Mercy Rooms: The First Door is a chilling psychological horror novel where grief becomes the monster, memory becomes the trap, and the greatest act of courage is choosing to keep living.
Perfect for readers who enjoy slow-burning supernatural horror, unsettling psychological suspense, haunted locations, and mysteries that linger long after the final page.
Welcome to the Mercy Rooms.
Just remember... every door opens both ways.
