Superheroes, spies, puzzle solversor all three?It's World War II, and Zenobia, Black Cat, and the other superheroes vanished from the streets of Philadelphia a couple of years ago. Josie, a white Irish immigrant, is despairing, with a war on and her beloved heroes all missing. At least Josie can do her part for the war effort, since a call has gone out for puzzle-solving and mathematically inclined kids. Just when it looks like Josie won't be able to helpare her excellent ciphering skills going to be ignored just because she's a girl?a mysterious woman solicits the help of Josie and two other puzzler girls: Akiko, a Japanese-American girl whose family is in an internment camp, and Mae, a black girl whose grandmother is a librarian, both also cipher- and comics-loving superhero fans. And somehow, when the three of them get together, they have powers! Like the heroes of their favorite comics, the girls whoosh through the skies, caped rescuers fighting Nazis. Along the way they meet and rescue the women who are the first computer programmers. Mae and Akiko encounter a smidgen of racism, although far, far milder than accuracy would call for; this is a superhero/puzzling/Nazi-thwarting tale, not historical fiction. With interwoven action sequences told in comics panels, the tale has the exciting pace of a superhero adventure.Puzzles readers can solve are the icing on this cake.
