Weeks later an anonymous novel about the voyage of the Miranda to the fabled Great Southern Continent causes a sensation. Ben decides to find the author everyone is talking about. He is sure the woman can help him - but she has disappeared. It is soon clear that Ben is involved in something more dangerous than the search for a reclusive writer.
