Doctor and writer, Ada Klein Fortuny (1975) is the pseudonym of the author of the essay The white plague(L'Otra, 2020), with which he entered the Catalan literary scene and in which he linked six writers and tuberculosis. Now he publishes his first novel, Lisa Cohen, a love story that relies on the epistolary narrative mechanism. We read a long letter to her lover—to whom she addresses herself as "my beloved lord"—written by Lisa, a woman who boards a train to Paris and reflects on ambition, inequalities, betrayals, desire, forgiveness, motherhood, prejudices, and the passage of time. At the same time, she takes stock of her lineage and the sisterhood that develops among friends. A letter that, evidently, she will never send.
