Aboard La Méduse, Sven the Terrible continues to discover treasures, board enemy ships and clash with Kit Malouf, his most formidable opponent. But for some time now, Sven has not been himself and no longer has his heart set on adventure. He is pale, drawn-looking and has lost all desire to play the pirate. This is a real problem when you are one of the most feared pirates on the seven seas. Sven needs a holiday, to unwind, recharge his batteries and rediscover his taste for adventure. But he will soon discover that it is not easy for a pirate to take a holiday.
