From the author of the “breathtaking, bone-chilling work of psychological suspense” (Cristina Alger, USA TODAY bestselling author) Her One Mistake, comes a twist-filled thriller following three ambitious women whose professional rivalries and personal secrets collide after a devastating fire threatens to expose the truth.

Returning to work after maternity leave, Laura expects to reclaim her role at the powerful advertising agency Morris and Wood. Instead, she finds herself sidelined by Mia, the woman hired to cover for her—and who now seems determined to stay. Despite Laura’s long-standing connection to the agency’s influential CEO, she struggles to regain control while juggling the pressures of career and motherhood.

Mia insists she’s only doing her job, but her desperation to remain at the firm runs deeper than anyone realizes. If her carefully guarded secret were revealed, everything she’s built could collapse overnight. Meanwhile, Janie, the wife of the agency’s founder, has sacrificed her own ambitions to support her husband’s success—and harbors a dark secret she will protect at any cost.

When a shocking fire rocks the agency, the fragile balance between the women shatters. As investigators circle and long-buried lies surface, each woman must decide how far she’s willing to go to protect her future.

With her signature “chilling, captivating” (Megan Miranda, New York Times bestselling author) prose, Heidi Perks weaves another bone-chilling and unputdownable thriller in the vein of Watching You and The Couple Next Door. Taut, chilling, and relentlessly suspenseful, this novel explores ambition, betrayal, and the dangerous power dynamics lurking behind polished office doors.
