Family, flight, and a fight for life.

Bestselling author Kent McInnis masterfully concludes his Sierra Hotel trilogy with Semper Fly, a gripping yarn exploring the aftermath of war and the enduring spirit of those who served.

In the wake of the Vietnam War, Rob Amity's life is a portrait of the American dream turned turbulent. After retiring from the U.S. Air Force, he finds prosperity in Oklahoma's oil boom and joy in his marriage to Suzy and her son Sean.

While Rob's passion for flying is reignited after a decade, his return to the skies is marred by a pattern of escalating harassment over his military service. When an ordinary father-son camping trip spirals into confrontation, he dismisses it as nothing more than macho bluster—but he couldn't be more wrong. Unbeknownst to Rob, he and his family have become pawns in a deadly game targeting veterans. Hunted down and kidnapped during a visit to the Grand Canyon, they're forced to confront just how deeply the scars of Vietnam still run. How could this have happened in the America they know and love? Will these wounds ever heal? And can they ever hope to fly home in peace, free from the ghosts of the past?
