Thorfinn the Nicest Viking series Books 4 to 6
The Disgusting Feast, the Raging Raiders and the Terrible Treasure
Prepare yourself for the wrath of the Norsemen! That is, if you don't mind and it's not too inconvenient... Thorfinn the Nicest Viking is a funny, illustrated, action-packed new 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!
