The Kids in Mrs. Z's Class: Emma McKenna, Full Out

From a New York Times bestselling author, cheerleader Emma McKenna is thrilled for her first day at a new school-but when her former best friend (now her enemy) shows up in class, Emma's quest to start over socially may take a tumble. Emma McKenna can't wait for third grade at the brand-new Curiosity Academy. She'll have a cool teacher who wears high-tops and science earrings. She'll meet interesting classmates from all over Peppermint Falls.
Best of all, she'll get a fresh start after last year's talent-show disaster left her with that awful nickname. It's going to be the best year ever! Then Lucy walks into Mrs. Z's room. Lucy, Emma's best-friend-turned-enemy. Lucy, who gave Emma that nickname and spread it all over school! Emma's fresh start is doomed .
