Shari, a highly gifted twelve-year-old girl detects an intentional signal hidden within the data of 31 ATLAS, an interstellar object which the world believes to be a meteor. Her suspicions are confirmed by her mentor, the psychic Patrice, who reveals that the object is an Ancient Traveller and is here on a mission to cosmically engineer the Earth's critical shift from the third to the fifth dimension.

As global events escalate, Shari realises that the vessel's mission is to activate a crystalline energy node deep in the Amazon rainforest. With the help of Ramiro, a sceptical logistician, Shari has 48 hours to get to the subterranean location and insert a Harmonic Algorithm into the Node to mediate the shift and hopefully avert a global crisis.
