A missing CIA officer. A rogue terrorist faction. A bioweapon more devastating than anything ever seen… And that’s just the beginning. When a rogue military faction in China kidnaps a CIA case officer, global tensions ignite. Desperate to forestall the looming firestorm, the United States deploys an elite team of Navy SEALs to rescue the agent, protected by nothing but their training and a single pilot providing air cover from his FA-18E Super Hornet—normally, it wouldn’t be enough. But these aren’t normal times…and this is no ordinary pilot. Fresh off his latest mission, TOPGUN pilot Colt Bancroft is tasked with providing air support to the SEALs. But when Chinese jets engage him just as a bioweapon is simultaneously deployed against Colt’s aircraft carrier, he realizes this is more than a simple kidnapping: it’s a prelude to world war.

And more importantly, how to stop them before they strike again. It’s a race between national security and global catastrophe...and only a man used to flying supersonic has a chance in hell of winning.
