The League of Secret Heroes Series

“Readers…will be enamored by this blend of history, mystery, and superpowered action.” —Booklist (starred review) “Has the exciting pace of a superhero adventure.” —Kirkus Reviews Hidden Figures meets Wonder Woman in this action-packed, comic-inspired adventure about a brilliant girl puzzler who discovers she’s part of a superhero team—the first in a new series! Josie O’Malley does a lot to help out Mam after her father goes off to fight the Nazis, but she wishes she could do more—like all those caped heroes who now seem to have disappeared. If Josie can’t fly and control weather like her idol, Zenobia, maybe she can put her math smarts to use cracking puzzles for the government. After an official tosses out her puzzler test because she’s a girl, it soon becomes clear that an even more top-secret agency has its eye on Josie, along with two other applicants: Akiko and Mae. 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—the human computers and earliest programmers called “the ENIAC Six”—this pulse-pounding adventure features bold action and brave thinking, with forty-eight pages of comic book style graphic panels throughout the book. Readers will want to don their own capes for an adventure, and realize they have the power to be a superhero, too!

“Pitch-perfect action scenes…A winning blend of comedy, superheroics, inspirational women from history, and puzzle-solving.” —Kirkus Reviews A trio of young superheroes try to thwart a spy in this second book in the action-packed, comics-inspired adventure series that’s Hidden Figures meets Wonder Woman! After defeating The Hisser—and discovering their power as a team—Infinity Trinity is ready for its next adventure. When Akiko, Mae, and Josie learn that a spy has been betraying secrets to the Japanese military, they join Room Twelve in San Francisco for important work with other code-cracking experts. But soon there is personal code to crack: Akiko spots her mom walking with the suspected spy through San Francisco, which had been her family’s home until Executive Order No. 9066 sent Akiko and all Japanese Americans on the West Coast into internment camps. Teaming up with brilliant members of The League of Secret Heroes—like real-life World War II code-crackers Genevieve Grotjan and Elizebeth Friedman—Akiko, Mae, and Josie search for answers as they battle the evil clown Side-Splitter, who’s bent on destroying not only the city, but the Infinity Trinity, too. As clues begin to pile up that her mother has become entangled with Side-Splitter’s sinister plot, can Akiko solve the most important puzzle of all?

When the Infinity Trinity hears of a Nazi spy plot that could bring danger to Chicago, Mae knows they must go to check on her beloved aunts, the daring World War II pilots Willa Brown and Janet Harmon. Mae’s Granny Crumpler isn’t exactly thrilled about her granddaughter and her friends trying to get involved with something so dangerous—especially when she’s already worried about not hearing from Mae’s dad, who is serving in Europe and fighting for freedom on and off the battlefield. But when Aunt Willa and Aunt Janet go missing, Mae knows that the sinister spy plot just got personal. They discover the evil Metallic Falcon has captured her aunts, and he is determined to thwart the Infinity Trinity’s ultimate quest to bring back Zenobia and all the missing superheroes safely. With the help of the Women Airforce Service Pilots (WASPs) and Room Twelve, Mae, Josie, and Akiko must use all their powers and code-cracking smarts in a challenge that will take them on a high-flying loop from Chicago to Sweetwater, Texas, to a final showdown in Paris. Can the Infinity Trinity soar to new heights and complete the biggest mission of them all?
