Suggest me cool sound engineer/physics books

Hello, im new here so please help me.
For my girlfriends birthday, I want to get her a book based on her special interests, which is physics and sound engineering, so if you read some, please give me the best ones you had.
Thank you so much :))
P.s. I need a book that I can order in Poland, no no-name author that you can only get through darkweb
