Meet Francois, the newest character in the Rochester series. Steven wasn't happy that house sitting for Principal Coley's sister included taking care of her spoiled cat. He would have downright refused if he'd known that the cat had a secret. Francois was a time traveler. While Mrs. Levine's class is learning about the past by exploring the Genesee Country Village and Museum, Francois leads Steven on a time traveling journey into a fire in Rochester's past and a test of his strength and courage.
