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.

When Chief Harald is poisoned by a putrid sleeping potion, Thorfinn suspects visiting soothsayer Ragwich. Banished for offending the power-hungry wise man, Thorfinn and his friends set sail to find the world’s best potion maker to brew a cure. Unfortunately, the antidote requires a very rare ingredient.

Can Thorfinn find the cure and wake Harald before Ragwich takes control of the village?

Thorfinn and the Putrid Potion is the eighth 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!
