A Sadie Gray FBI Mystery Series

Deep in the majestic Northern California woods, hidden in a remote hunting cabin, lies a secret too shocking for words: a mystery that could derail FBI Special Agent Sadie Gray’s career before it even starts. Grass Valley, California, is home to all sorts of people, their darkest secrets, and the shadows where they hide them. It was also the location of a series of abductions, including Sadie's abduction, spanning back nearly twenty years.

After barely surviving her first case in Grass Valley, FBI Special Agent Sadie Gray thought she’d seen the worst of humanity. She was wrong. Called to investigate a high-profile disappearance the FBI's San Francisco field office quietly passed over, Sadie and her handsome partner, Agent Brad Tulle, are thrust into a chilling new case—a mystery that stretches across state lines and defies logic. Leona Kolsch vanished without a trace… and the last confirmed sighting wasn’t in California. It was over 700 miles away—in Utah.

FBI Agents Sadie Gray and Brad Tulle are chasing their most terrifying case yet: someone is hunting social media influencers. The first victim, Briella Hughes—young, rich, and infamous for stirring up online chaos—is just the beginning. As more influencers meet the same grisly fate, Sadie and Brad uncover a chilling truth: this is no ordinary serial killer, and the message behind the murders is far darker and more divisive than they imagined.

When Sadie Gray worked her last assignment, she never expected that the end of one case would rocket her right into the next, but then the creep said her name, told her she was on his list. When Sadie and Brad are pulled into several murders, all seemingly related to an online group called The Murder Society, the game of cat and mouse becomes one of survival, for the hacker known only as “Monster” is throwing bodies at them, but he’s also tearing through Sadie’s private life.
