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 been dreaming of making her debut in a gorgeous white gown forever, if only she could find an escort.
Izzie, meanwhile, is still struggling to fit into Emerald Cove society and when troublemaking former-deb Dylan rolls into town, Izzie thinks she's finally found someone she can relate to. But 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.
