Tales of the Risen Tide

On a map redrawn by the rampant sea-level rise of the twenty-second century, survivors war over the ruins of high-ground whilst pirates and slavers plague the vast new seas that surround them.
But amidst the ashes of the world there remains a place for the young and the brave to call home: The Archon - a ship crewed by orphan thieves, escaped prisoners, and heretic runaways.
They are the Archonauts, and this is their tale.
A post-apocalyptic pirate adventure with the heart of an epic fantasy, Tales of the Risen Tide is the debut novel from British author David M Reynolds.
