A true-crime podcaster receives an unmarked package on his doorstep. Inside: five cassette tapes labeled like episodes—and a note that reads simply, "You're ready."

Marcus Cole has spent six years hosting Cold Trail, a podcast dedicated to unsolved cases. What his audience doesn't know is why he's really obsessed with cold cases: his mother was murdered when he was six years old. Stabbed seventeen times in their home. No witnesses. No forensic evidence. The killer was never found.

The first tape contains the audio recording of that night.

His mother's voice. His six-year-old self being tucked into bed. And then the sounds of someone entering the house—someone she knew, someone she trusted—followed by four minutes he can never unhear.

But this isn't just evidence of an old crime. As Marcus listens to the remaining tapes, he discovers that someone has been watching him his entire life. Guiding him. Shaping him. Taking credit for his scholarship. His career. His success. Claiming to have orchestrated everything he's ever achieved.

And now this person wants to meet.

When Marcus follows the instructions to a quiet family restaurant, he discovers the killer's identity—and realizes that the person he's trusted most in the world has been hiding the most devastating secret imaginable. But the restaurant's other patrons aren't just witnesses. They're something else entirely. And Marcus is about to learn that some families are bound by something far darker than blood.

The bayou has belonged to the Thibodaux family since great-granddaddy Obadiah carved this land from nothing. Ezekiel knows the stories—the parties, the elegance, the hundred and forty-seven souls who worked the plantation before the war. He mourns those glory days the way his grandfather taught him, drinking whisky in his pirogue and dreaming of when the world made sense.

Then the fog rolls in.

Thick and white, moving like something alive, it swallows everything until Ezekiel can't see ten feet in any direction. His boat drifts until it hits solid ground—an island that shouldn't exist, that has never appeared on any map, covered in old-growth oak and lit by fires where Black men and women have built something impossible: a community that has thrived for over a century, hidden from the world that wanted to destroy them.

They recognize his name. Thibodaux. The name his family gave them when they had no names of their own.

They remember everything: the ship. The auction block. The whip. The locked bedroom where Obadiah took what he wanted.

And now they have questions for Ezekiel. About who he is. What he believes. Whether the legacy he's so proud of deserves to continue—or whether it ends here, on an island where the sins of the fathers are finally answered.
