Sixth-grader Thomas Fallgrout is finally settling in at Pennybaker School, home of student unicyclers, thespians, acrobats, and other classmates with unique and unusual gifts. After a bit of an unusual start to the school year, things are finally starting to seem normal. As normal as they ever could be at this decidedly unusual school, anyway. Until his Facts After the Fact (aka History) teacher Mr. Faboo goes missing, right in the middle of his favorite lesson of the year, leaving the class not a clue as to why or how. And his Four Square (aka Phys Ed) teacher introduces a new unit that is decidedly distressing. And Thomas's neighbor, the formerly friendless Chip (he of the wacky sock collection), swoops in and bonds with all of Thomas's friends, leaving Thomas in the dust. This year is getting out of control, and it's up to Thomas to take matters into his own hands. It's time… for a revolution.
