The Other Mrs. Hale

When Sloane Hale opens the morning mail, one Visa charge changes everything. Forty-two hundred dollars at a Mercedes dealership in Rye-with a billing address that isn't hers. Her husband has a second wife. Instead of confronting him, Sloane does something far more dangerous: she infiltrates the other woman's life. Posing as a new arrival, she joins Anya's book club and engineers a friendship that begins as pure investigation.
and becomes something much more complicated. What starts as a domestic thriller about bigamy slowly transforms into a powerful story of two women discovering the courage to leave the life they thought they wanted - and finding each other in the process. Sharp, addictive, and emotionally devastating, The Other Mrs. Hale is a page-turning exploration of secrets, loyalty, and the moment a woman decides she's done pretending.
Perfect for fans of Gone Girl, The Last Mrs. Parrish, and smart sapphic fiction.
