Nutmeg Books for Lower School - Intermediate 2025: Chester Keene Cracks the Code

Chester Keene takes great comfort in his routines. Afterschool Monday to Thursday is bowling, and Friday, the best of days, is laser tag! But Chester has one other very special thing--he gets secret spy messages from his dad, who must be on covert government assignments, which is why Chester has never met him.
Then one day, Chester's classmate, Skye, approaches him with a clue. They've been tasked with a complex puzzle-solving mission. Skye proves to be a useful partner and good company, even if her free-wheeling ways are disruptive to Chester's carefully built schedule.
As Chester and Skye get closer to their final clue, they discover the key to their spy assignment: they have to stop a heist! But cracking this code may mean finding out things are not always what they seem.
