Different Worlds: A Journey Through Time

by L. Evermore

What if the key to the future... was hidden in the past?

Twelve-year-old Travis is stuck in the most boring summer of his life. His best friend is gone. His science project is toast. And now his mom wants him to volunteer at a retirement home?

But when he meets a mysterious scientist with a time machine in Room 217, everything changes.

Suddenly, Travis is traveling through history—meeting real-life legends like Nikola Tesla, Percy Julian, Charles Drew, and more. Each stop unlocks a piece of a powerful energy formula that could change the world—or destroy it if it falls into the wrong hands.

As Travis races through time, he’ll discover that science isn’t just about facts and formulas… it’s about choices. And sometimes, the future depends on the stories we choose to remember.

A fast-paced, mind-bending middle-grade adventure blending STEM, Black history, and time-travel thrills.
Perfect for fans of The Magic Treehouse, The Last Last-Day-of-Summer, and Rick Riordan Presents.
