The Moomins and the Great Flood (in the original Swedish it is The Little Trolls and the Great Flood) is a book written by Finnish author Tove Jansson in 1945. It was the first book to star the Moomins during the end of World War II, but is often seen as a prequel to the main Moomin books, as most of the main characters are introduced in the next book. This was the last Moomin book to be translated into English. It was published by Schildts as a limited hardback version in 2005, to celebrate 60 years of the Moomins.
