Remember that girl? The one who was impossibly cool, who taught you how to blow smoke rings, cut school, sneak out of the house? Remember how you turned yourself inside out trying to be just like her—and then she broke your heart? Set in the long, hot summer of 1973, Paula McLain's lyrical debut novel explores what happens when an insecure, motherless teenager falls under the dangerous spell of "that girl"—her older cousin Fawn. Fawn's worldly ways are mesmerizing to Jamie, who submits to a makeover—both inside and out—to win Fawn's approval. But over the course of a summer wrecked with tragedy and loss, Jamie learns that Fawn will use anything and anyone to further her own motives. When a local girl goes missing, Jamie realizes how dangerous Fawn truly is, and recognizes, too late, her own complicity in the disaster that unfolds around them. Paula McLain's poignant debut is a compelling family portrait that explores the darker sides of love and loyalty.
