After a Navy pilot inexplicably loses control of his stealth fighter, he stumbles upon a global conspiracy, and embarks on a thrilling chase filled with espionage and betrayal.

"A high-octane and adrenaline-powered thriller... Strap in and hold on!" --Jack Carr, Former Navy SEAL sniper and #1 New York Times bestselling author of the James Reece Terminal List series

TOP GUN instructor Colt Bancroft has just catapulted off the USS Abraham Lincoln, his F-35C Joint Strike Fighter trailing blue and yellow flame as he climbs into the night sky off the California coast.

When he is sent to investigate a series of mysterious lights floating dangerously close to his aircraft carrier, disaster strikes. His jet becomes unresponsive as it rolls inverted and enters a nosedive aimed right at the aircraft carrier's unsuspecting escort cruiser...

What follows is a tale of heroism and betrayal, spycraft and suspense, and aerial combat against an unexpected adversary.

To clear his name and unmask a traitor, Colt must survive a dangerous game of spy-vs-spy, where trusting the wrong person could cost him his life. To stop the enemy from hitting their ultimate target, Colt must use every ounce of his skill and training...and uncover the identity of the UNKNOWN RIDER.

From author Jack Stewart, a former US Navy Top Gun instructor pilot, comes an exhilarating military thriller that's packed with high-octane action and puts the reader behind the controls of a modern jet fighter. Perfect for fans of Tom Clancy and Dale Brown.
