Two girls, one summer, and a whole lot to learn from each other
 
Zara's an alpha - the first letter of the Greek alphabet. She's popular. I'm more like one of the obscure letters in the middle that no one's ever heard of - an omicron or something.

Zara, Tilly, and Mieke go to different schools and live in different social worlds. But for two weeks every summer they're the Indigo Girls - surfing, hiking, or just hanging out at the campground or the nearby resort. This year Mieke doesn't show up, and Zara and Tilly - the queen bee and the geek - are left circling each other, unsure how to relate without Mieke in the middle. Soon it becomes a summer of change and a summer of secrets; a summer for losing themselves but finding each other.
