# Poseidon's Wake Poseidon's Wake brings the Poseidon's Children trilogy to its far-future conclusion. Human civilization now stretches across the Solar System and onto extrasolar colonies, but expansion has stalled under the watch of alien powers and the political compromises that followed humanity's first great wave into space. Then an impossible signal arrives from empty, unexplored space with a single instruction: send Ndege Akinya. The message pulls disgraced scientist Ndege Akinya and several other factions into the same crisis. Some see the signal as a scientific breakthrough, some as a political threat, and others as a chance to break the limits that have held human expansion in check. Preparing the expedition means dealing with sabotage, competing ideologies, and the unresolved legacy of Eunice Akinya's discoveries. Where Blue Remembered Earth begins with a family inheritance, Poseidon's Wake ends with a civilization-scale reckoning. Reynolds ties the Akinya story to questions of faster-than-light travel, first contact, and whether humanity is capable of growing beyond its own divisions. The result is a finale about discovery, ambition, and the cost of becoming a truly interstellar species.
