Halvdan, Meia and the monk Do have left England behind and head for Iceland. But a fire-breathing mountain has erupted! For Mr Egil, the richest man in Reykjavik, it is a disaster. This means that he cannot retrieve the sword that he has promised to his soon to be son-in-law. Without the sword, no wedding! In Mr Egil’s house there is also a shaman, who immediately accuses Havdan, Meia and Do of causing the outbreak and want to sacrifice them to the gods. Will Meia and Halvdan manage to find the sword and bring it back in time for the wedding? They embark on yet another adventure with cunning and courage.

Halvdan the Viking is a series by Martin Widmark and illustrator Mats Vänehem, about the young boy Halvdan who finds himself in one adventure after the other, together with his friend Meia.
