The Unknowns by Benedict Carey is about two kids who follow these math clues that their abducted math tutored/adult friend, Mrs. Clarke, has left behind. These clues supposedly lead them to the Folsom Energy plant where some plan is being formulated to run the inhabitance, of their small town of Adjacent, away for their own special needs. Now it is up to these two kids, Di and Tom, and some friends they meet along the way to put a stop to this so the citizens of Adjacent can continue to live in their peaceful town.
