Attie McAllister has never been one to sit still. With a NASA scientist mom training for a mission to the International Space Station, an FBI agent dad heading on a covert assignment in Europe, and her adventurous Aunt Loxley unraveling forgotten history, Attie is used to life moving fast.

But when she stumbles upon an old photograph of students from Carnegie Mellon-The Six-her curiosity takes over. As Attie balances her e-bike invention, her best friend's growing YouTube channel, and a new obsession with project management, she realizes she's not just chasing history-she's racing against time. With clues showing up in the unlikeliest of places, Mom uncovering dangerous truths at NASA, and Dad navigating global tensions, Attie and her best friend Jenny must document, decode, and disrupt before it's too late.

Because if The Six were silenced before they could finish their work... What will happen now that Attie is piecing the clues together?
