About The Book

Wonder Woman meets Hidden Figures in this action-packed adventure trilogy about a trio of young superheroes fighting for justice during World War II!

In the midst of World War II, Josie, Akiko, and Mae are chosen by a top-secret agency to help crack puzzles for the government. The trio bonds over their shared love of female superhero celebrities, from Hauntima to Zenobia to Hopscotch. But during one extraordinary afternoon, they find themselves transformed into the newest (and youngest!) superheroes in town. As the girls’ abilities slowly begin to emerge, they learn that their skills will be crucial in thwarting a shapeshifting henchman of Hitler, and, just maybe, in solving an even larger mystery about the superheroes who’ve recently gone missing.

Inspired by remarkable real-life women from World War II, this pulse-pounding adventure series features bold action and brave thinking, with forty-eight pages of comic book–style graphic panels throughout each book.

This exciting and empowering hardcover boxed set includes:
