Matt Haig books for 9 year old anxious DD

[goteam]

DD is 9, a bit of a worrier, loves reading fiction and I have heard that Matt Haig's books might fit the bill. Any suggestions? I'm not familiar with his books.

Matt Haig writes for both children and adults. Some of his adult books deal with anxiety, but they’re non-fiction and not really appropriate for a 9yo. His children’s books are fiction and are great reads but aren’t remotely to do with anxiety and so I wouldn’t recommend them if that’s something you’re particularly after.
I’d recommend Perfectly Imperfect Stories, The Goldfish Boy, Wonder and Swan Song by Gill Lewis.

Thanks @Ricekrispie22 I will look into those suggestions
