Finn Family Moomintroll - Tove Jansson. My other favourite moomin book. All the adventures that ensue the summer Moomintroll and his friends find the magical Hobgoblin's hat.
Tove Jansson (b. 9 August 1914) was a Swedish-speaking Finnish novelist, painter, illustrator and comic strip author. Jansson is best known as the author of the Moomin books for children. http://en.wikipedia.org/wiki/Tove_Jansson
