The girl becomes a prisoner of Zola, her father’s sworn enemy on the Luna ship. To return home, the diver must lift many precious stones from the seabed. The team heads towards Bastian, a great city in the Nameless Sea. It is there that the girl learns about a rare stone that has only been seen once—the night owl. She is forced to make a deal and find him in exchange for her father's life. As Fable is lured into a world of lies and betrayal, she learns that the dark secrets her mother took to her grave now have the power to harm the people she cares about. To save them, the girl will have to risk everything that she has only recently acquired.
