\"More original and entertaining than most mystery and adventure novels, the story is immediately involving. The fast-paced first-person narrative shifts, chapter by chapter, between Iris and Ike, setting the stage, introducing the intriguing characters, and laying the groundwork for upcoming volumes in this engaging book in the National Archive Hunters series.\" Booklist, Starred Review

\"A high-energy story that holds its own in the growing pantheon of middle-grade crime thrillers.\" Kirkus Reviews

Absolutely spectacular. Kids are going to go wild for this series. Jarrett Lerner, award-winning author of A Work in Progress and the EngiNerds series
