Pandemonium in Puzzle Town by B. A. Johnson

The stranger in Puzzle Town has everyone talking. When he gets off the bus, his frumpy old suitcase simply says Kevin. He looks normal, but in a town where everybody has knobs, Kevin has no knobs! He is too different! Where can he live? Who would ever want to be his friend? Then a powerful force enters Puzzle Town, and their world spins out of control. How will Kevin ever become a true citizen of Puzzle Town when he just doesn’t fit in?
