Did you know that orange cats are almost always boys? It's true. And cats that are three colors-white, black, and brown-are usually always girls? It's science. Eight-year-old Emma McGraw loves science. She also loves being an only child and living with her mother in their cozy little condo. So when four-year-old Anthony moves in for a while (into her room!), Emma isn't too happy. He may be cute, but he can't keep his hands off her stuff! And Anthony isn't only a problem at home. Now that Emma is in a new school, she'd like to make some friends, yet how can she invite anyone over when annoying Anthony is there? But Emma's in for a surprise. As the days pass, she begins to realize that having a "little brother" around is a lot more fun than she ever thought it could be. Filled with over fifty adorable illustrations, Only Emma is sure to wriggle its way into readers' hearts.
