This viking duo will give Horrid Henry a run for his money! Francesca Simon had so much fun writing about two truly awful viking children (HACK AND WHACK) she has decided to take the pair, now older, on further adventures - pitching the stories squarely at the Horrid Henry readership. Set in the snowy fjords of a Viking kingdom, the terrible pair are adored by their proud parents for causing havoc and demonstrating that they are the very best worst vikings. But of course, behaving appallingly often goes wrong: getting lost and ransacking their own village by mistake, ruining birthday parties and upsetting your friends . . . With whip-smart dialogue, and accompanied by Dennis the Menace style anarchic cartoon imagery, this series is as sharp, funny and compelling as you would expect from the reigning Queen of Comedy.
