Don't Wake The Night Mortician - Nightlock Sins, #18

The door said don't. She didn't listen.

Forensic photographer Florence Wren breaks into the Harrowgate Mortuary at 2:00 AM with one goal: to see her sister's body one last time. But when she opens drawer seven, the face staring back at her isn't Rosalind's. It's a stranger, scheduled for cremation in exactly 72 hours to destroy the evidence of a horrific underground organ-harvesting conspiracy.

Before Florence can run, the building locks down.

Enter Malvern Pike, the enigmatic, solitary night mortician who owns the facility. Malvern has spent the last two years quietly tracking the corrupt medical clinic responsible for the body-swapping operation. But his investigation hides an even darker secret. For the past eight months, Malvern has been obsessively watching Florence from the shadows, cataloging her every habit, scent, and move. Anticipating her arrival, he has built and fully stocked a hidden apartment tailored perfectly to her preferences right above the morgue—a gilded cage designed to keep her close.

Now, forced into proximity within the cold, isolated walls of the mortuary, Florence has 72 hours to unravel the mystery and find out if her sister is still alive. To do it, she must form a dangerous alliance with a morally grey mortician who sacrificed her sister's immediate safety to build a long-term trap.

Malvern gave her the key to his building and all his darkest secrets. But as the clock ticks down, Florence must decide if she can trust a man whose meticulous obsession might be the only thing keeping them alive—or if the most dangerous thing in the mortuary is how much she wants to stay.
