Set against the deep-sea technology revolution of 2045, this story combines four elements: hard science fiction, international power struggles, ancient civilizations, and interstellar suspense. As humanity faces a fight for deep-sea resources, the revival of an ancient AI, and the shock of signals from an extraterrestrial civilization, it must make choices that will determine its survival. With a hard-edged narrative about technology safeguarding civilization, the novel also blends patriotic feeling with philosophical reflection.
