In 1789 struggling writer Ben Dearlove rescues a woman from a furious Covent Garden mob. The woman is ill and in her delirium cries out the name "Miranda". 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. Who is the woman and what is she running from? Who is following Ben? And what is the Admiralty trying to hide? Before he can discover the shocking truth Ben has to get out of prison, catch a thief, and bring a murderer to justice.
