About the Book

A riveting thriller where one man must face the unimaginable, perfect for fans of Jack Carr and Mark Greaney.

In the middle of a routine flight to Anchorage, the unthinkable happens.

North American Airways Flight 164 is ordered by an unidentified agency to divert into Jackson Hole, Wyoming, minutes ahead of a nuclear first strike against the United States.

Captain Cole Shepherd carries the grief of a lost daughter, the wreckage of a failed marriage, and the lives of 187 passengers as he attempts to land his Airbus A321XLR on a runway too short and on borrowed time.

An aurora burns bright against the shadow of the Tetons, an unnatural byproduct of the first strike. Two passengers, a doctor with a classified case and the armed government escort at her side, seem to be the reason he was given the warning at all.

It took a nuclear strike to remind Cole Shepherd he still had something to lose.

Now he has to decide who to trust, and how far he'll go to stop what comes next.

Perfect for fans of Brad Thor, Mark Greaney, and Ben Coes, Unknown Sky is the debut technothriller from a U.S. Navy veteran and Airbus captain who flies the exact aircraft you'll read in the book.

About the Author

Kyle is a U.S. Navy veteran who now flies the Airbus A320 family for a major U.S. carrier.

Unknown Sky, his debut, is the first novel in the Cole Shepherd series. It began as a simple question on a long overnight flight to Anchorage: what would a crew actually do if the world ended somewhere between top of climb and top of descent?

Before the airlines, Kyle served in the U.S. Navy, an experience that shaped Cole Shepherd's former life as a submarine XO and gives the novel's operational detail the weight of things actually witnessed rather than researched. Readers who care whether the fuel numbers close, the checklist flows are right, and the airport diagrams match the real thing will find Kyle takes that as seriously as they do.

He writes in the tradition of Jack Carr, Marc Cameron, and Tom Clancy, with a Cormac McCarthy undertone that runs beneath the technical surface. Unknown Sky is ultimately a book about a man who needed the end of the world to remember why he wanted to be in it.

Kyle lives in Arkansas with his family.
