Four teenagers. One impossible device. Twenty-four hours to save history itself.When Emma Clarke and her friends discover a mysterious metallic disk buried beneath their school, they think they've found an interesting historical artifact. They're wrong. It's a Chrono Compass-an ancient device that can transport people through time for exactly 24 hours.One accidental activation later, they're stranded in Ancient Egypt with no way home and a countdown ticking in their minds. But they're not alone in the past. A shadowy organization called the Architects is hunting them, determined to claim the Compass and rewrite history according to their vision of "perfection." Standing against them are the Keepers-scattered guardians across time who believe every moment, good and terrible, matters.Now Emma, Leo, Riley, and Mia must survive the scorching desert, decode three-thousand-year-old warnings, and locate a powerful crystal before time runs out.

Their very existence.With each hour, something they love disappears.The Chrono Compass launches an epic adventure series where smart kids face impossible odds, ancient mysteries hide futuristic technology, and every choice echoes through time. Fast-paced, cinematic, and emotionally gripping, this is time travel with real consequences-where courage means accepting loss, friendship means sharing pain, and saving the world requires sacrificing pieces of yourself.The war for time has begun. And four unlikely heroes just became humanity's last defense against a future without choice.Book 1 of the Chrono Explorers series. Perfect for middle grade and young adult readers aged 10-16.
