Clementine can't believe her ears â " her beloved teacher, Mr. D'Matz, might be leaving them for the rest of the year to go on a research trip to Egypt! No other teacher has ever understood her impulsiveness, her itch to draw constantly, or her need to play â Beat the Clockâ when the day feels too long. And in his place, he's left a substitute with a whole new set of rules that Clementine just can't figure out. The only solution, she decides, is to hatch a plan to get Mr. D'Matz back. If it means ruining her teacher's once-in-a-lifetime chance -- well, it's worth it. Isn't it?
