Amy Whey is proud of her ordinary life—teaching diving lessons, baking cookies for new neighbors, helping her best friend, Charlotte, run their local book club. Her greatest joy is her family: her devoted professor husband, her spirited fifteen-year-old stepdaughter, her adorable infant son. But Amy’s sweet, uncomplicated life begins to unravel when the mysterious and alluring Angelica Roux arrives on her doorstep one book club night. Sultry and magnetic, Roux beguiles the group with her feral charm. She keeps the wine flowing and lures them into a game of spilling secrets. Everyone thinks it’s naughty, harmless fun. Only Amy knows better. Something wicked has come her way—a she-devil who seems to know the terrible truth about who she is and what she once did. When they’re alone, Roux tells her that if she doesn’t give her what she asks for, she’s going to make Amy pay for her sins. To protect herself and her family and save the life she’s built, Amy must beat the devil at her own clever game.
