The Spartan Sacrifice cover

Whoever Controls the Past Writes the Future.


Seventeen-year-old Dan Renfrew and his partner, Sam Cahill, know that stopping Victor Stahl's ruthless quest for global domination means risking another journey into the past. This time, their mission takes them to ancient Greece, on the eve of one of history's most legendary battles: Thermopylae.


Outnumbered by the vast Persian army, the Spartan warriors and their allies are preparing to make their desperate stand. But as the armies gather and the fate of Greece hangs in the balance, a horrifying accident threatens to unravel history itself.


Suddenly, Dan and Sam face a danger even greater than Victor Stahl's sinister plans. With the historical timeline at risk and the battle drawing closer, they must navigate a world of fierce warriors, shifting loyalties, and deadly consequences to prevent a catastrophe that could change the future forever.


As time runs out, the young adventurers must confront an impossible question: What are they willing to sacrifice to save a history that has already been written?


Combining thrilling action, historical intrigue, and the high stakes of time travel, The Spartan Sacrifice is an unforgettable adventure for teen and young adult readers who love epic battles, unexpected twists, and heroes willing to risk everything.
