Forced by necessity into a life of piracy, Senlin and his crew struggle to survive aboard their stolen airship. Senlin’s search for his lost wife continues, even as her ghost hounds his every step. But the Tower of Babel proves to be as difficult to reenter as it was to escape. While searching for an unguarded port, Senlin encounters the camp of Luc Marat, who seems equal parts bandit and humanitarian. One thing is for certain: his asylum for the downtrodden hods is not as peaceful as it appears. In desperation, Senlin turns to the mysterious and dangerous Sphinx, with whom Edith shares a terrible bond. They discover the Sphinx’s help does not come cheaply. Senlin must choose between his friends, his freedom, and his wife.
