The Best Bad Day Ever by Marianna Coppo

Today is a terrible day for Wolfie: it's cloudy (there is a single cloud), the water in the bubble bath is ice cold, there aren't enough chocolate chips in the cookies, and everyone else seems to be having an amazing day (lucky them). No one understands Wolfie at school. But then Penguin comes along... and she does understand. Suddenly things start to get a whole lot better. 

This is a story about how when you're feeling misunderstood, sometimes all it takes to change your perspective completely, is a like-minded friend.
