I tell people I didn't become an adult until my parents died, and I was thirty-nine when my mom died. So I wasn't a child, but I really look back and think I became an adult that moment when my last parent passed away. Maybe that doesn't say great things about me, but that's just kind of how I look back on my whole life. I don't think I was super immature, but at the same time, the way that I thought about the world really changed when they were gone. I guess that's grief, but it's also giving you tools to go on and to help the next generation.

Mark Greaney is a #1 New York Times bestselling author and has spent his career exploring the technical and human complexities of the modern thriller. A student of international relations and political science, he has spent the last two decades at the intersection of deep-state espionage and the high-tech future of warfare. He is the creator of the Gray Man series, a motion picture starring Ryan Gosling, and was entrusted to carry forward the Jack Ryan universe created by the late Tom Clancy. To get the details right, Mark doesn’t just sit at a desk; his writing is built on a foundation of immersive experiential research. He’s traveled to dozens of countries, trained with SWAT teams, and even flown in Navy fighter jets.

His latest book, The Hard Line, brings his protagonist back to a landscape of old conflicts in Northern Ireland and forces him to confront a father he hasn't seen in twenty years. It’s a story about the blood we share and the blood we shed. It arrives at a moment when the boundaries of global conflict are being redrawn by AI, disinformation, and a shifting geopolitical order.
