She moved in next door. She brought casseroles, compliments, and the kind of friendship Blythe Calloway didn't know she needed.
Sloane Averill is everything Blythe is not-confident, effortless, magnetic. Within weeks, she's Blythe's closest friend. Within months, she's inside every corner of Blythe's life: her marriage, her daughter, her wardrobe, her mind.
But Sloane Averill doesn't exist.
The woman next door is Camille Duval-Blythe's half-sister, born from an affair Blythe's mother buried thirty years ago. She didn't come to Laurel Heights to make a friend. She came to claim the life she was denied.
By the time Blythe discovers the truth, Camille has already taken what matters most. And the worst part isn't the betrayal.
The worst part is that Blythe misses her.
A twisting, suffocating thriller about the lies women tell each other-and the bigger lies they tell themselves.
For readers of Freida McFadden, Lisa Jewell, and Gillian Flynn.
