On a stormy night in New York City, the power goes out in the Liu family home. As Jennifer and Daniel sit by candlelight with their grandfather, Dr. Liu tells them about Nikola Tesla, the brilliant inventor who imagined a future transformed by electricity.

Soon, a mysterious invitation from Dr. K arrives, and the children step through the time portal into Tesla's world.

In nineteenth-century New York, Jennifer and Daniel enter laboratories filled with coils, motors, wires, and remarkable experiments. With Tesla and Dr. K as their guides, they discover the difference between alternating current, AC, and direct current, DC, and learn why the battle over how electricity should be delivered became known as the War of the Currents.

Their journey brings science to life as they explore circuits, electromagnetic induction, the Tesla coil, and the possibilities of wireless energy. They also witness the spectacular World's Columbian Exposition, where electric light illuminates a vision of what the future might become.

But Tesla's story is about more than inventions. Jennifer and Daniel discover a scientist who faced skepticism, setbacks, and fierce competition while continuing to pursue ideas others thought impossible.

Through experiments, questions, and an unforgettable journey into the past, they learn that scientific progress requires careful observation, persistence, imagination, and the courage to keep exploring.

Travel through time. Follow the science. Discover Nikola Tesla and the electric dreams that helped power the modern world.
