It's time for the gowns to go on and the gloves to come off.

Isabelle Scott and Mirabelle Monroe are still reeling from the knowledge that they're not cousins after all -- they're sisters. But with cotillion season right around the corner, the girls barely have time to process the news. Mira has always dreamed of making her debut in a gorgeous white gown, but now that she has broken up with Taylor, who's going to be her escort? Izzie, meanwhile, is still struggling to fit into Emerald Cove society, and when the troublemaking former debutante Dylan rolls into town, Izzie thinks she's finally found someone she can relate to. However, as cotillion preparations heat up, there are dance steps to learn, manners to perfect, and secret initiations to complete -- as if sophomore year wasn't hard enough.
