Sumnertime!

Spunky, vivacious Sumner Donovan, a Grade 11 student at huge Buena Vida High School, is getting ready for her CalPro, a big student project that every junior must complete. Sumner wants to do hers on vintage clothing and Mexican poverty, but her guidance counselor says no; she must do her project as the promotions person at KPLC, the school's beleaguered radio station. Sumner knows zero about radio and cares even less, but her counselor is adamant--the girl must spend three months at the station, promoting it so that everyone at big, bustling Buena Vida High knows about KPLC, 99.9 FM.
