Las Hormigas by Bernard Werber

Two interwoven narratives trace a human mystery and the microscopic dramas of an ant colony: as people probe a strange, deadly secret linked to a recently inherited apartment, the book plunges into the inner life of ants, portraying their communication, social organization and ruthless survival strategies in vivid, often unsettling detail. The juxtaposition of human behavior and insect collective intelligence turns a speculative, scientific curiosity into a tense, philosophical exploration of society, conflict and what it means to be intelligent.
