The League of Secret Heroes travel to Paris on their most critical mission yet in this third book in the action-packed, comics-inspired adventure series that’s Hidden Figures meets Wonder Woman ! 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.

Chapter Two BRAVERY ISN’T ABOUT BATTLING BACK supervillains. Most of the time, being brave means looking at the things that scare us and pushing past them.      Like spiders. Or thunderstorms. Or making a mistake.      “Mae Eugenia Crumpler!” came a shout. “What in the world are you doing here in Chicago, Illinois? Did you run away from that summer camp?”      At the sight of what must have been her granny, Mae’s eyebrows shot so high, they could have bumped a bird passing overhead. And her mouth started moving, but no sound came out. I gave a jump too. Not only because the sudden appearance of a little old lady yelling at us was surprising. But also because that little old lady looked so tiny and fragile and, well, sweet.      She seemed like somebody who’d serve us a plate of warm cookies. Not yell at us like a drill sergeant in the army.      Mae’s granny peered over her horn-rimmed glasses, eyes ablaze.      “What do you have to say for yourself, Mae Eugenia?” she said, waving a knobby finger in our direction.      How could we explain where we’d been all this time? And even if we did explain it—that we’d fought off a supervillain called Side-Splitter and his army of evil clowns, that we’d saved innocent people and maybe even the whole city of San Francisco from Side-Splitter’s destruction, that we’d helped catch a spy who was sending secret messages to the Japanese military, and that we’d discovered Akiko’s mom was working to beat the Nazis with Room Twelve, too, just like us—Granny Crumpler wouldn’t believe it.      I barely could myself.      “Anybody want a candy bar?” asked Akiko, clearly trying to divert attention from speechless Mae.

When we were supposed to be at a sleepaway camp somewhere in the woods near Philadelphia! I shot her the stink-eye.      “Santa’s Village?” asked Granny Crumpler. “Where’s that?”      “Right,” Akiko said, finally catching on. She shoved the last chocolate bar back into her bag. “Um. Santa’s Village. It’s… umm… north. Of… Philadelphia.”      I wanted to smack my forehead. This was not going well.      “Mae Eugenia, I received word from Mrs.-what’s-her-name. Mrs. Bow, Mrs. Bah—”      “Mrs. Boudica,” Mae said, finally a
