We can't choose our weather, but we can choose what we make of it.

Arwel is having a fine day. Yes, his sister has gone off to school for the first time, leaving him alone, and yes, there's a cloud above his head. But he is fine, really he is...

But the cloud grows, looms, gets in his way - until Arwel has to admit: there's a Storm-Cat outside and it's waiting for him!

But after a spectacular storm comes the comforting calm in this special picture-book debut from the illustrator of Zadie Smith and Nick Laird's Weirdo.
