When a flood sweeps through the valley, the Moomins must find a new house. And with typical Moomin good luck, one just happens to be floating by. It looks normal enough, but there are curtains where one wall should be, strange rows of lights, and other odd amenities. Then Moomintroll and the Snork Maiden disappear, and the family realize that the house may hold the answers to more than they ever dreamed.
- Book #4
Tove Jansson (1914–2001) was born in Helsinki and spent much of her life in Finland. She is the author of the Moomin books. Born into an artistic family―her father was a sculptor and her mother was a graphic designer and illustrator―Jansson studied at the University College of Arts, Crafts and Design in Stockholm, the Finnish Academy of Fine Arts, and L'École des Beaux-Arts in Paris. In addition to her Moomin books, she also wrote several novels, drew comic strips and worked as a painter and illustrator. In 1966, she was awarded the Hans Christian Andersen Medal for her body of work. Jansson had a studio in Helsinki but spent most of her time at her home on a small island called Klovharu.
