The text is direct and straightforward, with not a wasted word, providing access to a wide age range of children. Whether the cloud represents anxiety, incessant worry, depression, or simply the facing of fears is up to interpretation, despite the flap text. Whichever it is, children will understand that it is about emotions and that Willy is confronting something. Browne’s many fans and libraries looking for more books on emotions will find a lot to appreciate here.

The theme is conveyed in a way that is developmentally pitch-perfect for young readers who often have big feelings that no one can just fix. Browne deftly shows that emotions can arrive suddenly and, more importantly, leave again without any reason why.
