"I expected a lot from Navy veterans Andrews and Wilson--and they exceeded every expectation! Tom Clancy Act of Defiance is a remarkable tale of political intrigue and high-seas adventure. Jack Ryan and friends are in capable hands."
--Marc Cameron, New York Times bestselling author of Tom Clancy Command and Control

"Tom Clancy Act of Defiance slips into the Clancy franchise with the skill and deftness of the Dallas dropping into the baffles of the Red October. For long-time fans, the nostalgic moments hit all the right notes. For new readers, the gripping story features the latest tech but doesn't overwhelm. For the purists, Andrews and Wilson write with the authentic voice and steady hand of men who have "been there, done that" in the real-world. In short, it's a great read. I highly recommend it."
--Mike Maden, New York Times bestselling author of Tom Clancy Enemy Contact

"If Tom Clancy was still alive, this is the book he'd write. Author duo Andrews & Wilson give military thriller readers what they've spent 40 years longing for: a tale of submarine warfare that builds upon the seminal Clancy masterpiece, Hunt for the Red October. Tom Clancy Act of Defiance is simply magnificent."
--Don Bentley, New York Times bestselling author of Tom Clancy Weapons Grade and Forgotten War

"Echoes of Tom Clancy's The Hunt for Red October reverberate four decades after the late author's famous debut... Well-paced excitement as the Ryans come through again."
