The final war has begun. They have defeated the pirate Coronado, and the traps set for them on Coral Island. Now Rachel Cain and Morgan Reid face their deadliest foe, Captain Vance Devlin and his pirate fleet. Together with the pirate queen Calypso, they sail to Cambridge, the legendary Kingdom of Gold, to prevent Devlin from laying claim to the city and the riches within. But are they too late? Devlin's spies are everywhere: at sea and on land, and a band of his cutthroats have invaded the Kingdom of Gold. Their goal: to seize the castle and capture the king. The age of adventure is coming to an end. Final battles will be fought with sword and with cannon fire. And before one last arrow pierces the evening sky, there will be fire, and there will be thunder.
