New Girl, The (Go Girl!)

Zoe can't wait to meet Isabelle, the new girl. What will she be like, and will they be friends? No matter what, Zoe is going to make sure Isabelle feels welcome at their school. But it turns out Isabelle has no trouble fitting in right away. And when she starts being really mean, Zoe has to choose between being mean too, or standing tall and being a good friend.
