TEN FOR EVERY ONE begins in the aftermath of a mysterious Vietnam War battle, one in which all but three American Green Berets were brutally and surprisingly killed. Jump to thirty years later, and teenagers Emily, Charlie, and Sergio (children of the three surviving war heroes) are grappling with both the weight of their parents' legendary status and the widespread speculation on how their parents managed to survive. However, the teenagers' lives are forever changed when their parents vanish during a State Department trip to Vietnam, paralleling the unsolved disappearance of Sergio's father in the same jungle ten years prior on a W.H.O. mission.

Left to navigate the fog of unanswered questions, Emily, Charlie, and Sergio set off on a daring international quest to uncover the truth behind their parents' enigmatic past. Delving deeper into the mystery of the famous Vietnam War battle, they unearth startling revelations and adversaries determined to bring dark plans to fruition. As the teenagers find themselves in the midst of an ancient conflict, they must race against time to rescue their parents and help their new allies dismantle the sinister conspiracy that threatens to take over the world.
