"In the outer settlements of the human-occupied solar system, there are rumors about what was found deep under Neptune's frozen seas when a Hungarian billionaire's ship was lost with all hands. But the rumors are far more tame than the reality. When the billionaire's daughter mounts a mission to find the truth, her discoveries will up-end humanity's understanding of our origins on Earth"-- In the far reaches of the solar system, the outer planets-- billions of miles from Earth, unknown for millennia-- are being settled. Neptune, the ice giant, is swathed in clouds of hydrogen, helium, and methane and circled by rings of rock and dust. Three years ago Ilona Magyr's father, Miklos, disappeared while exploring the seas of Neptune. Everyone believes he is dead: crushed, frozen, or boiled alive in Neptune's turbulent seas. With legendary space explorer Derek Humbolt piloting her ship and planetary scientist Jan Meitner guiding the search, Ilona Magyr knows she will find her father alive on Neptune. The discover of the wreckage of an alien ship deep in Neptune's ocean changes humanity's understanding of its future... and its past. -- adapted from jacket Provided by publisher.
