Since the very first Horrible Histories titles were published back in 1993, history books for children have never been the same. The appeal of all things wicked, weird and woeful has proven to be a huge hit and the series is now a world-wide bestseller. Not only are these books filled with horrible stories, there are also curious quizzes, rotten recipes, gruesome games and terrible tests! Vicious Vikings is packed with frightening facts about these vile invaders and their savage Saxon enemies — from cruel kings and vengeful Viking warriors to the suffering slaves. Written by Terry Deary.
