Charlie Thorne, a brilliant young code-breaker, is thrust into a global race against the Furies, a dangerous group seeking Einstein's hidden equation.

In this high-stakes adventure, trust is scarce, and the clock is ticking.

From the publisher

“Fast-paced, smart, and action-packed…a real page-burner.” –Chris Grabenstein, #1 New York Times bestselling author of the Mr. Lemoncello’s Library series From New York Times bestselling author Stuart Gibbs comes the first novel in a thrilling new series about the world’s youngest and smartest genius who’s forced to use her unbelievable code-breaking skills to outsmart Einstein. Charlie Thorne is a genius. Charlie Thorne is a thief. Charlie Thorne isn’t old enough to drive. And now it’s up to her to save the world… Decades ago, Albert Einstein devised an equation that could benefit all life on earth–or destroy it. Fearing what would happen if the equation fell into the wrong hands, he hid it. But now, a diabolical group known as the Furies are closing in on its location. In desperation, a team of CIA agents drags Charlie into the hunt, needing her brilliance to find it first–even though this means placing her life in grave danger. In a breakneck adventure that spans the globe, Charlie must crack a complex code created by Einstein himself, struggle to survive in a world where no one can be trusted, and fight to keep the last equation safe once and for all.
