Gabby, Billy, Izzie, Andy, and Sean—each bursting with their own personality, strikingly different looks and talents, in sports, science, and the arts. Each drawn by the magical spark of connection that happens to the young. At the exclusive Atwood School, on a bright September day, starting in kindergarten they become an inseparable group known to outsiders as the Big Five. In this rarefied world, five families grow closer, and five children bloom beside one another, unaware of the storms gathering around them.
