Only If You're Lucky is a sharp and twisty exploration of female friendship from the New York Times bestselling author Stacy Willingham. The story follows Lucy Sharpe, a character who is larger than life—magnetic, addictive, bold, and dangerous. Especially for Margot, the shy and careful one, who becomes Lucy's roommate during their freshman year at a liberal arts college in South Carolina.

Margot, previously always the sidekick and never the center of attention, is drawn into an off-campus house with three other girls: Lucy, the ringleader; Sloane, the sarcastic one; and Nicole, the nice one. These opposites but deeply intertwined characters lead Margot to finally break out of her shell, a shell she's been in since her best friend Eliza's death just after high school.

As Margot and Lucy grow close, a fraternity boy from the house next door is brutally murdered, and Lucy Sharpe goes missing without a trace. What ensues is a tantalizing thriller that delves into themes of friendship, belonging, loyalty, envy, and betrayal. Stacy Willingham delivers another gripping novel that cements her position as a standout author in psychological suspense.
