Jessi's Secret Language (the Baby-Sitters Club #12)

By: Chan Chau

Jessi recently moved to Stoneybrook and is one of the newest members of the Baby-sitters Club. She's getting ready to start regularly sittings for the BSC's newest charge, Matt Braddock. Matt has been deaf since birth and uses sign language to communicate, so Jessi has to use it, too. It's a secret language.
