This is the Hundred-and-forty-third in my one-book-at-a-time bookshelf.
Moomins hibernate. Makes it awkward to set your story in the middle of winter, and what a tragedy if Jansson couldn't take advantage of the Finnish winter landscape as a backdrop for a Moomin story.
Don't fret. She finds a way, and the result is another terrific book. Perhaps my favourite. If one is allowed to have favourites. Certainly Moomintroll gets lots of air time, and Little My (just the best anti-hero).
Everything I know about a real winter with snow I learnt from this book. Perhaps one day I will see the real thing. One day.
