The Adventures of Tintin chronicles the exploits of the intrepid young reporter Tintin, whose relentless pursuit of a good story thrusts him into a world of high adventure. Along with his faithful canine sidekick Snowy, and the blustery sea dog Captain Haddock, Tintin travels the globe, averting danger at every turn to discover the secret of the fabled ship The Unicorn.

Susan, John, Jane and David are caught up in a new adventure. This time they try to tackle a malevolent weather witch who is sending storms to batter the country. With terrifying winds and flooding everywhere, only they have the skills to stop it, for these are not ordinary children. Witch-craft runs in their family. This is their first contact with a witch outside their own family - and she is older, stronger and so much more powerful than them. So who will win the battle for the weather? Can they work together to defeat her? What will Gran do? This adventure will test them all as never before, and will teach them more about witchcraft than they had ever dreamed existed.

King Ottokar's Sceptre (French: Le Sceptre d'Ottokar) is the eighth volume of The Adventures of Tintin, the comics series by Belgian cartoonist Hergé. Commissioned by the conservative Belgian newspaper Le Vingtième Siècle for its children's supplement Le Petit Vingtième, it was serialised weekly from August 1938 to August 1939. Hergé intended the story as a satirical criticism of the expansionist policies of Nazi Germany, in particular the annexation of Austria in March 1938 (the Anschluss).
