You are cordially invited to the Secret Book Society... London, 1895: Trapped by oppressive marriages and societal expectations, three women receive a mysterious invitation to an afternoon tea at the home of the reclusive Lady Duxbury. Beneath the genteel facade of the gathering lies a secret book club--a sanctuary where they can discover freedom, sisterhood, and the courage to rewrite their stories. Eleanor Clarke, a devoted mother suffocating under the tyranny of her husband. Rose Wharton, a transplanted American dollar princess struggling to fit the mold of an aristocratic wife. Lavinia Cavendish, an artistic young woman haunted by a dangerous family secret. All are drawn to the enigmatic Lady Duxbury, a thrice-widowed countess whose husbands' untimely deaths have sparked whispers of murder. As the women form deep, heartwarming friendships, they uncover secrets about their marriages, their pasts, and the risks they face. Their courage is their only weapon in the oppressive world that has kept them silent, but when secrets are deadly, one misstep could cost them everything.
