The year is 859. A Viking fleet travels to Seville, one of the richest cities of the time, with the goal of razing and looting it. However, everything is in failure, and the northern warriors are captured by the governor of the city, who demands an inordinate ransom for their release. When the news reaches their village, the women decide not to surrender and, together with some children and slaves, hire a small group of mercenaries who will teach them how to fight. A year later, the rescue expedition will be ready to set sail. It seems like an impossible mission that will be fraught with misfortune and adversity. With great narrative agility and an exhaustive knowledge of the time, I. Biggi transports us to the world of the Vikings in a raid that reached our shores.
