A former captain gnawed by a debt to the Brotherhood, Archibald Kerig took refuge on the island of Fidj, among the Sorkass, a people of cannibal hunters. Raised like his granddaughter, Caëtliss took the bar of the "Brissant" to redeem his honor. When a key recovered in a wreck leads her to the Bank of the Gouffre, she awakens a secret buried: a contract in Kraken's skin linking the master of the Waves and the Emperor of the Monts-Cieux. At the helm of his city-ship, Captain Daraghen, a dog of war of the Brotherhood, sets the island on fire and blood to recover it. Between an old dishonored sailor, a young captain ready to do anything for his own and Sorkass, the battle of the "Brissant" against the "Fureur-des-Océans" will seal the fate of piracy.
