About this listen

It's been years since the Gray Man's first mission, but the trouble's just getting started in the latest entry in the number one New York Times best-selling series.

Before he was the Gray Man, Court Gentry was Sierra Six, the junior member of a CIA action team.

In their first mission, they took out a terrorist leader, at a terrible price. Years have passed. The Gray Man is on a simple mission when he sees a ghost: the long-dead terrorist, but he's remarkably energetic for a dead man.

A decade of time hasn't changed the Gray Man. He isn't one to leave a job unfinished or a blood debt unpaid.

Featured Article: The top 100 series of all time


The feeling of discovering that your favorite new listen is actually the start of a series is euphoric. That you can immediately hit play and re-enter a beloved new world, or love story, or era from history is a gift to the devoted listener. But how to pick just 100 of these unique and immersive listening journeys? We defined a series as having a minimum of three books, and—after some debate—we decided the titles had to be anchored in fiction. From YA to horror to historical fiction, from fresh voices to seminal tales, hours of discovery await.
