Tajemnica starej skrzyni

Long awaited continuation of the book „Czekoladowy dziadek”. This time, the most ordinary Norwegian children, Martin and Matilda Siuersen, go to visit their grandfather Oscar. Oscar was not nicknamed the Chocolate Grandpa for nothing, as he is a terrible sweet... tooth and cannot live without candies and chocolate. As always, with the Chocolate Grandpa, the children are in for incredible adventures: they travel through time, meet real Vikings, and search for a stolen chest that holds a magical artifact capable of granting any wish, but only one. It’s very important to find the chest in time, as it has fallen into the hands of the cunning Paulsen sisters, who hate sweets and dream of destroying them all over the world. Will they succeed in their plan, or will Martin, Matilda, and the Chocolate Grandpa manage to stop them in time? Read the book - and find out.
