Thorfinn and the Dreadful Dragon (Thorfinn the Nicest Viking)

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 up. Too bad his dad is Harald the Skull-Splitter, the roughest and toughest Viking of them all. Vikings far and wide are traveling to the great Fire Festival where they'll compete to become 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?
