Kids Book Suggestions

Hi Reddit, I need your help.

I want to buy a book for my 10-year-old sister’s birthday, but I have no idea what to get her. She loves reading Dory Fantasmagory and Geronimo Stilton books, and she is also into STEM subjects like math and science. Do you have any suggestions for funny, engaging, and educational books for her age group? I want to get her something she will enjoy and learn from, not boring or too easy.

I really appreciate any help you can provide.
