Eight-year-old Ruby Booker is the baby sis of Marcellus (11), Roosevelt (10), and Tyner (9), the most popular boys on Chill Brook Ave. When Ruby isn't hanging with her friend, Theresa Petticoat, she's finding out what kind of mischief her brothers are getting into. She's sweet and sassy and every bit as tough as her older siblings. She sings like nobody's business; she has a pet iguana named Lady Love; her favorite color is grape-jelly purple; and when she grows up, she's going to be the most famous woman animal doctor on the planet. She's the fabulous, oh-so-spectacular Ruby Marigold Booker!
