Cracking the code isn't all it's cracked up to be in this scavenger hunt adventure from a Coretta Scott King Honor-winning author.

Chester Keene takes great comfort in his routines. Afterschool Monday to Thursday is bowling, and Friday, the best of days, is laser tag! But besides Friday laser tag, 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 at lunch, Chester’s classmate, Skye, approaches him with a clue. They’ve been tasked with a complex puzzle-solving mission. Chester takes their assignments very seriously, but Skye treats it like a big game. Skye proves to be a useful partner and good company, even if her haphazard, free-wheeling ways are disruptive to Chester’s carefully curated 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.
