Septina Nash is a 7th grade seventh child with purple hair and a knack for popping up in music videos. After her triplet-sister mysteriously disappears, Septina finds herself stalked by penguins, pursued by a mad scientist, and on the fast track to an Olympic medal in freestyle skateboarding. Along with her more reality-minded triplet-brother, Quinn, Septina hurdles from one adventure to the next: surviving for ten minutes in the world’s most dangerous truck stop, launching a polar expedition, and collecting an enormous amount of empty yogurt containers. Is it any wonder why she can’t complete her math homework on time?
