From the western coast of Salamandastron, they arrive to the high shores of the North: Captain Rake Blackfur and his hares of the Watch Squad, along with Skor the Deadly Ax and the Crew of sea otter pirates. Feel free to rush towards the mesmerizing saga, songs, feasts, reckless courage and battles! Set sail on the grim ship "Green Shroud" with sea rats and corsairs led by Captain Razzid Wearat, the terror of land and sea! His goal is to capture the Abbey! Has there ever been such a bloody and menacing race before? The fate of Abbot Tibb and his Redwallians hangs in the balance. Who will be the first to reach the gates, who will save the legendary Abbey from the clutches of Wearath? Forward, forward, to victory or death!

The author reproduced the conflict between predators and noble animals of Salamandastron and the Northern Coast. A couple of Redwall residents go on a journey of news and trouble. A race begins between predators and armed good-natured people, the goal of which is the abbey. Only this time the forest dwellers have more to solve military-strategic problems than to guess some ancient puzzle, or discover the secret of the sunk generations of animals - there are no such mysteries here. The Abbey is no longer a thing in itself, it has no secret weapons hidden somewhere in the gatehouse scrolls, and even Martin's famous sword does not become a lethal weapon against the pirates' key figure.
