The Last Signal - Dan Brown

\nTHE LAST SIGNAL\n \nA NOVEL BY DAN BROWN\n \n\n For millennia, the stones have stood in silence. \n\n When Jack Crane and Lauren Brown uncover a strange mark hidden within the Eye of the Sahara, they trigger a chain of discoveries stretching across the world's most ancient monuments-Stonehenge, the Great Wall of China, the Pyramids, Chichén Itzá, even Gobleki Tepe. Each bears the same symbol. Each point to something never meant to be found. \n\n They are not temples. They are not tombs. They are signals. \n\n As unseen watchers close in and time itself seems to tighten, Jack and Lauren begin to understand the truth: humanity has faced extinction before-and someone knew it would happen again. \n\n The Last Signal is a haunting, globe-spanning mystery about what our ancestors left behind... and whether the world is ready to hear their warning. \n\n
