Whoever Controls the Past Writes the Future
Seventeen-year-old Dan and his partner Sam know that their only chance to stop Victor Stahl’s in his quest for global domination is another jump into the past. This time, they find themselves in ancient Greece on the eve of one of history’s most famous conflicts: the Battle of Thermopylae. Heavily outnumbered by the massive Persian army, the Spartan warriors and their allies are girding themselves for war when a horrible accident threatens the fabric of history itself. In a race against time, Dan and Sam must battle to prevent a catastrophe far worse than Victor’s sinister plans. "The Spartan Sacrifice" is perfect for teen and young adult readers who love time travel, epic battles, and fast-paced adventures.
