A vanished hijacker. A rogue physicist. A secret war across time.

When Ethan Wallace cracks the code to time travel, he doesn’t tell the world. He builds a mission—one that leads straight to the unsolved mystery of D.B. Cooper, the man who hijacked a plane in 1971 and disappeared without a trace.

But Ethan isn’t the only one bending time.

As he digs deeper, he’s pulled into a shadow conflict involving a secret government agency, a charismatic fugitive, and a rival time traveler who knows more about Ethan’s future than he should.

With history unraveling and every jump risking catastrophic paradox, Ethan must outwit enemies across decades—or lose everything, including himself.
