Fiction by Fredrick Backman.
Now this was an unusual book. It's told from the point of view of a seven-year-old girl, who has a very special relationship with her --um... how shall I put this? oh yeah!-- wacko grandmother. Stories told from a child's point of view can be challenging, but the author did a great job with this one. I loved the characters, and it was really interesting!
Also this novel was originally written in Swedish, and although I don't usually care for translated works, the translation was amazingly good. I actually believed it was a British story.
