Sebastian, the one and only son of the king of England, is running for his life. Meanwhile Captain Walker is preparing his crew to raid the next cargo ship they've been targeting. These two very different people whose paths would've never usually crossed are about to meet. And this is their story.

Enter a dangerous, magical realm on the brink of rebellion, where the loyalty of the Guardians means power... or death. What happens when one Guardian turns her back on the Heir? Can Solangia survive? Or will it be pulled apart by scheming nobles and desperate rebels? Among traitors, thieves, assassins and mages, Morane must choose whether she will live up to her title as the Royal Thief or join the revolution-- and quickly, for she is not the only one making plans. Time is running out until the rebels strike, until the Heir rises, until her loyalty is tested. Who will survive, and who will fall? In this breathtaking adventure of high fantasy every path is fraught with danger, and no one is as they seem.
