Book excerpt: Meet Jenny — a teen who confides in her diary about what it is like to live with Ezra, her younger brother with autism, and her life with the most "wacky, exasperating, infuriating, amazing younger brother! If living with Ezra weren't hard enough, Jenny must deal with school bullies, rude classmates, and fragile friendships. But with the promise of a summer writing program and an Ezra-inspired project, Jenny finds the courage to be more than just "Ezra's sister, protector, defender, and his best and only friend," and loosens the invisible cord just enough to follow her own dreams. Includes a Note to Readers.
