Prepare yourself for the wrath of the Norsemen! That is, if you don't mind and it's not too inconvenient...

Everyone knows Vikings are ruthless barbarians whose idea of a good time involves pillaging, plundering and feasting. But Thorfinn is no ordinary Viking! He is always polite and happily offers to wash the dirty dishes. Too bad his dad is Harald the Skull-Splitter, Village Chief and the roughest and toughest Viking of them all.

Vikings far and wide are travelling to Scotland's Shetland Islands for the great Fire Festival where they'll compete to become the ultimate champion by creating dazzling fire displays. Chief Harald is determined to be victorious but it seems as if Thorfinn has ruined their chances against rival Viking Chief Magnus the Bone-Breaker, until he remembers a story about a once-legendary dragon, now in hiding…

Can Thorfinn and his ragtag crew track down the dreadful dragon and persuade her to help them put on a winning performance?

Thorfinn and the Dreadful Dragon is the seventh adventure for Thorfinn the Nicest Viking in this funny, action-packed illustrated series for young readers which bridges the gap between Horrid Henry and Diary of a Wimpy Kid, set in a world where manners mean nothing and politeness is pointless!
