Reach for this book when your daughter feels like an outsider or is struggling to find a peer group that appreciates her unique, perhaps unconventional, talents. It is the perfect remedy for the 'middle school slump' where children often feel they must hide their true selves to fit in. The story follows Ananka Fishbein and a group of five other highly gifted girls who discover a secret city beneath New York and form the Irregulars, an elite team of scouts and spies. Beyond the fast-paced mystery, the book explores themes of loyalty, self-reliance, and the power of finding a 'tribe' of like-minded friends. While it contains elements of crime and peril, it remains firmly grounded in the middle-grade space. It empowers readers to see their quirks as strengths and their curiosity as a superpower. It is an ideal choice for a child who craves adventure but also needs to see that being different is exactly what makes them extraordinary.
