Book suggestions for 7 year old girl

Hi there,

I'm hoping someone can help me. My goddaughter has recently really enjoyed reading and she's loving Jacqueline Wilson The Butterfly Club. I really love thats she's found this interest and I want to encourage her by reading more and picking up some good recommendations for her.

I'm pulling out some of my age appropriate favourites from the Wilson era, but I wondered if anyone had any recommendations of other authors?

I loved Enid Blyton myself and the malory tower series when I was younger but I'm trying to gauge if that's age appropriate. I'm in my late twenties now myself with no kids and struggling to judge. Thank you so much.
