"Worlds of the Ummah" is an intellectual fiction about ancient memory, lost connections and the fragile bridge between science, myth and love. And this is modern Israel, where the authors of the novel, Karina and Taya, a doctor and a journalist live. Two former lovers, meeting by chance years later, set off a chain of events that takes them beyond their usual world — into a space where artificial intelligence, ancient myths, personal guilt and lost intimacy are intertwined into a single whole. In the center is the Ummah. A mysterious female entity from the distant past, encased in an artifact that reacts to emotions, generates images and... seeks dialogue. "Worlds of the Ummah" is a novel about the pain of loss and the possibilities of return, about a woman's memory scattered over thousands of years, about the journey between reality, dreaming and digital sleep. This is a subtle, vivid, sometimes searing story of two worlds — the outer and the inner, the world of the future and the world of the long-forgotten. In this novel, philosophy is juxtaposed with a thriller, irony with piercing longing, and love with the inability to fully understand everything. This is a story about how one encounter — even an impossible one — can change the perception of life itself.
