1702, and in the lawless Caribbean sea young Matthew Loftus vows to captain his ship, the Cornelius, by honest trade rather than piracy and plunder.  But his crew lusts after the spoils that the fast, well-armed ship can win and the discontent begins to rumble.  Pursued by the English Navy on a false charge of mutiny, Matthew must evade the King’s ships and escape the attention of the ruthless privateers.  His only chance of pardon rests with a secret almanac that promises that great prize: to solve the Longitude.  But is the almanac what it seems?
