Zoe and her best friend, Olivia, have always had Big Plans: They'll tour the world as prima ballerinas and live in a swanky Manhattan apartment (where they'll hang out with their fabulous boyfriends, of course). But when they're cut from the ballet company, their plans for the future evaporate. Suddenly, Zoe's dodging cheerleaders who want her and Olivia to go out for the squad, and Olivia's got a crush on Calvin Taylor, who Zoe can't stand. Zoe can't imagine anything worse happening . . . until Olivia gets sick. Really sick. Suddenly, not being able to dance is the least of their problems.Olivia has always been the nice one, the happy-go-lucky one. Zoe has always been the snarky one, the look-on-the-dark-side one. But when your best friend is in the hospital, you better learn to step up fast. Now Zoe needs to put on a brave face and be the positive one. Even when Zoe isn't sure what to say. Even when Olivia misses months of school. Even when Zoe starts falling for Calvin.The one thing that keeps Zoe moving forward is knowing that Olivia will beat this thing, and everything will go back to the way it was before. It has to. Because the alternative is too terrifying for Zoe to even imagine.
