Lara Lington has always had an overactive imagination, but suddenly that imagination seems to be in overdrive. Normal professional twenty-something young women don't get visited by ghosts. Or do they? When the spirit of Lara's great-aunt Sadie - a feisty, demanding girl with firm ideas about fashion, love, and the right way to dance - mysteriously appears, she has one request: Lara must find a missing necklace that had been in Sadie's possession for more than seventy-five years, because Sadie cannot rest without it. Lara and Sadie make a hilarious sparring duo, and at first it seems as though they have nothing in common. But as the mission to find Sadie's necklace leads to intrigue and a new romance for Lara, these very different "twenties" girls learn some surprising truths from and about each other.
