Interesting maths books, 9 year old

[nonicknameseemsavailable]

Daughter number one is 9 and is interested in maths, not actually doing maths but the fascinating of it if that makes sense. Other than the murderous maths books does anyone have any recommendations of books please to do with maths or science. She has enjoyed the Uncle Albert books and the murderous maths ones, not read all of those yet, we have the box set but trying to get her to read other books is hard work whereas she is keen with these so if there are any others I am happy to try and get old of them for her. Her school also makes them read when they finish their maths (I don't agree with this as I think a maths lesson should be maths) so at least if she had a maths related book to read it would be a vaguely more appropriate use of her time. Thanks

Basher Science series have an Algebra and Geometry book.

Aimed at 10+. My kids have enjoyed the physics and chemistry books. They are a dip in and out format with a lot of (not very relevant tbh!) illustration.
