Smatrollen och den Stora Oversvamningen is very easy to read (ofc it's a childrens' book) and has well deserved its place as a Finnish classic. This is the first book that I read in swedish and I learnt a lot of new things. The book has all that you need: lovable characters, adventure and beautiful rich wording. I would read this to my kids (if I had any) and I know they would love it.
