Twenties Girl (original) Sophie Kinsella

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.
