How to Cheat a Dragon’s Curse (English, Paperback, Cressida Cowell)

Fishlegs has been struck with deadly Vorpentitis. The only cure is rare and almost impossible to find – a potato. But where on Berk will Hiccup find such a thing? He’ll have to dodge Sharkworms, battle Doomfangs and outwit crazy Hooligans if he’s going to be a hero again.
