A nice book about worry/anxiety. It can be helpful to talk about it with children, but at the same time it is «disguise» in some sort of «creepy little horror» that makes it fun and not too heavy. I really like the drawing, but a have a mixed feelings about the execution of the subject/story, because while I enjoy and find the concept really interesting, it was lacking the little sparkle that would have make it really captivating from start to finish. I think it could be helpful with some kids, but I also think some will lose interest/attention before the end. That’s why I drop my rating a bit.
